In the system that we are proposing, quality assessment of milk samples is achieved by real-time AI-based processing of speckle pattern images acquired using a camera, by illuminating small volumes of the fluid under test with laser light. \r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\">\r\nLaser speckle is the granular interference pattern produced by coherent light scattered from a diffusing fluid, such as a suspension, or surface, and consists of a random distribution of bright and dark spots. We plan to excite speckle patterns with multi-wavelength illumination and to investigate instrumental configurations working in reflection or in transmission, with the aim to find the most efficient source-sample-detector deployment scheme. Sequences of images of the speckle pattern are dense in information that needs to be pulled out: we want to demonstrate that, by smart data processing methods, several parameters can be extracted and correlated with the main properties of the milk sample under test (e.g. content of lipids, carbohydrates and proteins, and state of adulteration of the milk).\r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\">Among the plethora of algorithms available to process image data, we propose to adopt machine learning and deep learning models that we believe are the most promising. By using them, we plan to directly elaborate visual data without the need of a specialized hand-designed processing pipeline. We aim to design an embedded platform that can control the acquisition devices (camera and laser) and process acquired images using AI-algorithms. The prototype will include the necessary hardware to perform laser speckle imaging and processing in a compact fashion, while keeping in mind the affordability of components.<\/p>\r\n<p><a href=\"#link10\" target=\"_blank\" rel=\"noopener noreferrer\">\r\n    Back to top \u2191\r\n  <\/a><\/p>\r\n\r\n<\/body>\r\n<\/html> \t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f8253b4 elementor-widget elementor-widget-image\" data-id=\"f8253b4\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.6.2 - 04-04-2022 *\/\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\t\t\t\t\t\t\t\t\t\t\t\t<img width=\"1091\" height=\"410\" src=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/SP.png\" class=\"attachment-full size-full\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/SP.png 1091w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/SP-300x113.png 300w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/SP-1024x385.png 1024w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/SP-768x289.png 768w\" sizes=\"(max-width: 1091px) 100vw, 1091px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-95cdcfd elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"95cdcfd\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-7af5291\" data-id=\"7af5291\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-5af615c elementor-widget elementor-widget-menu-anchor\" data-id=\"5af615c\" data-element_type=\"widget\" data-widget_type=\"menu-anchor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div id=\"link2\" class=\"elementor-menu-anchor\"><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-009415d elementor-widget elementor-widget-html\" data-id=\"009415d\" data-element_type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<!DOCTYPE html>\r\n<html lang=\"en\">\r\n\r\n<style>\r\n\r\n\r\n  .project-sub-title {\r\n    font-weight: bold;\r\n    margin-bottom: 20px; \/* spazio tra titolo e caselle *\/\r\n    margin-top: 0px; \/* spazio tra titolo e caselle *\/\r\n    font-size: 1.2rem;\r\n    text-align: center; \/* titolo centrato *\/\r\n    color: \t#2F5597;\r\n  }\r\n\r\n<\/style>\r\n\r\n<body>\r\n\r\n\r\n\r\n<div class=\"project-title\">The ACOUSTIC project<\/div>\r\n  \r\n<div class=\"project-sub-title\">Development of integrated circuits, algorithms and mechano-acoustic technologies to transform generic surfaces into radiant acoustic elements with very high efficiency<\/div>\r\n\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 0px; \">\r\nThe project (N.ro MISE F\/310010\/01\/X56) is founded by the <strong>Ministry of Enterprises and Made in Italy <\/strong>\r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\">\r\nStarted on January 2023.

In particular, our recent works are focused on the implementation of smart and biocompatible micro-opto-fluidic sensing platforms based on NIR-SWIR spectroscopy (wavelength range: 1000 nm \u2013 2500 nm). The figure below shows the optoelectronic instrumental configuration used to distinguish harmful ethylene glycol from isopropanol in the NIR wavelength region.  We are moving towards the development of sensors for the quantification of fluids composition using short-wave infra-red (SWIR) spectroscopy, exploring wavelength regions up to 2 micrometers. Such sensors can be applied in several fields, from pharmaceutics and chemical to food quality and safety.

In Ring lasers different regimes have been theoretically predicted and experimentally observed, including bistability between the two clockwise, counter-clockwise (CW\/CCW) modes. A telemeter can be designed based on this regime.  \r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\">Indeed, suppose that at a given time the laser is in the CW regime. The radiation emitted from one ring-laser end (right end in Fig.1) is reflected back by the target and after a round trip time, which depends on the laser-target distance, it re-enters the laser cavity in opposite direction and, for proper operating conditions, switches the laser to CCW. The laser emission from the other output (left end in Fig.1) is directed toward a nearer (and fixed) local mirror along a short optical path to switch the laser back to CW, so that the operation can start again, producing a periodic variation of the power direction inside the cavity, which can be detected, for example, by a photodiode positioned behind the local (partial) mirror. Since the first round trip time depends on the laser-target distance, while the second is constant, the laser-target distance can be measured from the oscillation period.<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\"><a href=\"#link10\" target=\"_blank\" rel=\"noopener noreferrer\">\r\n    Back to top \u2191\r\n  <\/a><\/p>\r\n<\/body>\r\n<\/html> \t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-fbd8575 elementor-widget elementor-widget-image\" data-id=\"fbd8575\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img width=\"1788\" height=\"547\" src=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Laser-Telemetry-1.png\" class=\"attachment-full size-full\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Laser-Telemetry-1.png 1788w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Laser-Telemetry-1-300x92.png 300w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Laser-Telemetry-1-1024x313.png 1024w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Laser-Telemetry-1-768x235.png 768w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Laser-Telemetry-1-1536x470.png 1536w\" sizes=\"(max-width: 1788px) 100vw, 1788px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-204f34a elementor-widget elementor-widget-html\" data-id=\"204f34a\" data-element_type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<!DOCTYPE html>\r\n<html lang=\"en\">\r\n\r\n\r\n<body>\r\n\r\n\r\n\r\n\r\n\r\n\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\">A different scheme, based on the same operating principle, can be implemented using an electronic circuit to emulate the suitable regime of the ring laser.

The basic approach to chaos secured data transmission consists in hiding a message into the very complex noise-like waveform generated by a chaotic laser (Fig.1).  This can be done simply superposing chaos to the message at the transmitter (Tx), in order to strongly reduce its SNR. The composite signal is then transmitted through the fibre link. Message recovery is usually based on a master\/slave synchronization scheme: another laser (the slave, SL) is used at the receiver (Rx), and its parameters are matched with those of the transmitter laser (the master, MS). The composite waveform (chaos + message) from the optical link is injected into the slave. Under suitable operating conditions the slave laser to synchronizes to the master chaos, (i.e., the two devices generate almost exactly the same chaotic waveform), without, however, synchronizing the message. Then, the message can be extracted by making the difference between the received composite signal and the recovered chaotic waveform (Fig.2). The degree of matching required for efficient synchronization is significantly high. A suitable pair of devices (\u2018twins\u2019) has to be selected in close-proximity from the same wafer. This laser pair represents the (hardware) cryptographic key.\r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px; margin-top: 5px;\"><a href=\"#link10\" target=\"_blank\" rel=\"noopener noreferrer\">\r\n    Back to top \u2191<\/a><\/p>\r\n<\/body>\r\n<\/html> \t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-739c881 elementor-widget elementor-widget-image\" data-id=\"739c881\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img width=\"1848\" height=\"630\" src=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Optical-Chaotic-Cryptography.png\" class=\"attachment-full size-full\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Optical-Chaotic-Cryptography.png 1848w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Optical-Chaotic-Cryptography-300x102.png 300w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Optical-Chaotic-Cryptography-1024x349.png 1024w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Optical-Chaotic-Cryptography-768x262.png 768w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Optical-Chaotic-Cryptography-1536x524.png 1536w\" sizes=\"(max-width: 1848px) 100vw, 1848px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-556ee8c elementor-widget elementor-widget-html\" data-id=\"556ee8c\" data-element_type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<!DOCTYPE html>\r\n<html lang=\"en\">\r\n\r\n<body>\r\n\r\n\r\n  \r\n<div class=\"project-sub-title\">Chaotic lasers provide Physically Unclonable Functions for network authentication<\/div>\r\n\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 0px; \">Physical Unclonable Functions (PUFs) have been proposed as an alternative to standard authentication protocols, especially for the Internet of Things applications.  With PUFs, secret data are derived from complex physical characteristics of ICs or other electronic devices. In the optoelectronic domain, semiconductor lasers are possible candidates for such method of authentication (Fig.1). If SL1,2 have very well-matched parameters (twin lasers), in suitable operating conditions they produce the same chaotic modulation, i.e., they synchronize. A bit sequence can be easily obtained from the chaotic lasers by photodetection and digital processing (Fig.2). The response in the unsecure environment is the bit stream produced by Slave SL2 (Authorized  vs. Adversary). The reference response in the secure environment is the bit stream generated by SL1. Only if the two responses match authorization is granted.\r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px; margin-top: 5px;\"><a href=\"#link10\" target=\"_blank\" rel=\"noopener noreferrer\">\r\n    Back to top \u2191<\/a><\/p>\r\n<\/body>\r\n<\/html> \t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-07dd101 elementor-widget elementor-widget-image\" data-id=\"07dd101\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img width=\"1793\" height=\"557\" src=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Physical-Unclonable-Functions-1.png\" class=\"attachment-full size-full\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Physical-Unclonable-Functions-1.png 1793w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Physical-Unclonable-Functions-1-300x93.png 300w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Physical-Unclonable-Functions-1-1024x318.png 1024w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Physical-Unclonable-Functions-1-768x239.png 768w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Physical-Unclonable-Functions-1-1536x477.png 1536w\" sizes=\"(max-width: 1793px) 100vw, 1793px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-4283e9c elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"4283e9c\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-2ecb08d\" data-id=\"2ecb08d\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-475665e elementor-widget elementor-widget-menu-anchor\" data-id=\"475665e\" data-element_type=\"widget\" data-widget_type=\"menu-anchor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div id=\"link6\" class=\"elementor-menu-anchor\"><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-fe13ed2 elementor-widget elementor-widget-html\" data-id=\"fe13ed2\" data-element_type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<!DOCTYPE html>\r\n<html lang=\"en\">\r\n\r\n<body>\r\n\r\n\r\n\r\n<div class=\"project-title\">Completed Projects<\/div>\r\n  \r\n<div class=\"project-sub-title\">The Digital Smart Fluidic project: Artifical nutrition monitoring at home<\/div>\r\n\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 0px; \">Artificial nutrition at home is a research topics that the Digital Smart Fluidic (DSF) project focuses on.

Optical resonances of these low-cost optical resonators correspond to the positions of steep phase jumps on the interferometric cosine signal acquired with an optical spectrum analyzer. To the best of our knowledge, it is the first time that this method is employed for the detection of the wavelength positions of optical cavity resonances.\r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 0px; \">The figure above shows the optoelectronic instrumental configuration based on interferometry. We successfully demonstrated that the capillary can be inserted in a microoptofluidic setup and the wavelength positions of the steep jumps in the cosine signal depend on the RI of the filling fluid. The spectral phase shift interferometric technique can be efficiently employed for sensing the RI of ultralow volumes of fluids.\r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\">For more information see our publication in IEEE Transactions on Intrumentation and Measurement: <a href=\"https:\/\/ieeexplore.ieee.org\/abstract\/document\/9343308\" target=\"_blank\" rel=\"noopener noreferrer\">\r\n    click here!\r\n  <\/a>\r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\"><a href=\"#link10\" target=\"_blank\" rel=\"noopener noreferrer\">\r\n    Back to top \u2191\r\n  <\/a><\/p>\r\n<\/body>\r\n<\/html> \t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5b4c1ad elementor-widget elementor-widget-image\" data-id=\"5b4c1ad\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img width=\"1803\" height=\"753\" src=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Spectral-Phase-Shift-Interferometry-1-1.png\" class=\"attachment-full size-full\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Spectral-Phase-Shift-Interferometry-1-1.png 1803w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Spectral-Phase-Shift-Interferometry-1-1-300x125.png 300w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Spectral-Phase-Shift-Interferometry-1-1-1024x428.png 1024w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Spectral-Phase-Shift-Interferometry-1-1-768x321.png 768w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Spectral-Phase-Shift-Interferometry-1-1-1536x641.png 1536w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/Spectral-Phase-Shift-Interferometry-1-1-960x400.png 960w\" sizes=\"(max-width: 1803px) 100vw, 1803px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-507477e elementor-widget elementor-widget-html\" data-id=\"507477e\" data-element_type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<!DOCTYPE html>\r\n<html lang=\"en\">\r\n\r\n<body>\r\n\r\n\r\n  \r\n<div class=\"project-sub-title\">MOEMS Characterization and Piezoelectric Devices<\/div>\r\n\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 0px; \">In our laboratory, we develop advance optical systems to measure vibrations and to characterize micro-systems. To find the resonance frequencies and mode shapes of a micro-plate, an optical instrument for non-contact dynamic characterization is required. The dynamic response of micro-devices can be successfully characterized with optical methods based on interferometric measurements performed in just a few well selected spots on the structure. This approach is easily accessible and low-cost in comparison with conventional laser doppler vibrometers; therefore, we carried out the modal analysis of piezo-actuated microplates, which are buckled due to the built-in stress, using a compact, fiber-based interferometric setup.\r\n<\/p>\r\n\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\">For more information see our latest publication in Sensors and Actuators A: Physical: <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0924424722000826\" target=\"_blank\" rel=\"noopener noreferrer\">\r\n    click here!\r\n  <\/a> (In collaboration with the  University College of Southeast Norway) \r\n<\/p>\r\n<p style=\"text-align: justify; line-height: 1.65;\r\n    font-size: 1rem;\r\n    margin-bottom: 10px;\"><a href=\"#link10\" target=\"_blank\" rel=\"noopener noreferrer\">\r\n    Back to top \u2191\r\n  <\/a><\/p>\r\n<\/body>\r\n<\/html> \t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c26c322 elementor-widget elementor-widget-image\" data-id=\"c26c322\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img width=\"1803\" height=\"451\" src=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/MOEMS-Characterization.png\" class=\"attachment-full size-full\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/MOEMS-Characterization.png 1803w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/MOEMS-Characterization-300x75.png 300w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/MOEMS-Characterization-1024x256.png 1024w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/MOEMS-Characterization-768x192.png 768w, https:\/\/labeo.unipv.it\/wordpress\/wp-content\/uploads\/2025\/10\/MOEMS-Characterization-1536x384.png 1536w\" sizes=\"(max-width: 1803px) 100vw, 1803px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>The Laboratory of ElectroOptics at the University of Pavia conducts advanced research in the field of optoelectronics, in collaboration with Italian and international universities and companies.
