Conference: SPIE Photonics Europe<\/strong> <\/h2>\n\n\n\n

From 7 to 11 of April 2024, I. Montes-Gonz\u00e1lez and M. Canabal-Carbia assisted to the SPIE Photonics Europe<\/a> conference in Strasburg (France). <\/p>\n\n\n\n

They were delighted to show some of their recent research and connect with researchers of Photonics around Europe. They presented some of their work related to the use of polarimetric techniques emphasizing its potential to improve the visualization and identification of tissue in brain samples and the optimization and calibration of a Mueller matrix imaging polarimeter.<\/p>\n\n\n

Outreach Activity: <\/strong>Dissabtes de la F\u00edsica<\/strong> <\/h2>\n\n\n\n

On Saturday 2 March, the Optics Group opened their laboratories to high school students as part of the Dissabtes de la F\u00edsica<\/a><\/em> program. The students learned about the principles and applications of optics, such as polarization, diffraction, lasers and holograms. They also had the opportunity to interact with the researchers and ask them questions about their work.<\/p>\n\n\n\n
