High-resolution single-shot refractive index variation measurement using quadriwave lateral shearing interferometry (Conference Presentation)

Autor: Sherazade Aknoun, William Boucher, Benoit Wattellier, Antoine Federici

Publikováno v: High Contrast Metastructures IX.

Quadriwave lateral shearing interferometry (QWLSI) is a wave front sensing technology based on the analysis of an interferogram created by waves diffracted by an optical grating set in front of a camera sensor. Since QWLSI is a single-arm interferome

Thermal microscopy based on quantitative phase imaging for the study of heat-shock proteins at the single cell level (Conference Presentation)

Autor: Guillaume Baffou, Julien Savatier, Sophia Imperato, Antoine Federici, Benoit Wattellier, Sherazade Aknoun, Stephanie Vial, Serge Monneret, Hervé Rigneault, Julien Polleux, Jacob Verghese, Hadrien M. L. Robert

Publikováno v: Quantitative Phase Imaging V.

In response to heat stress, triggered by a temperature increase of just a few degrees, cells activate a mechanism called the heat-shock response. While conventional global heating processes lead to an overall and slow increase of the temperature, hea
