A video imaging device includes a light source (2), a detector (36), and an optical polarization system (6, 38) for video imaging of superfical biological tissue layers (26, 32). The device relies on taking a set of measurements at different polarization orientations so as to render a new image that is independent of the light (22) reflected from the surface (12) of a tissue sample (14) and that is independent of the light (34) scattered from deep tissue layers (32).
L'invention concerne un dispositif d'imagerie vidéo qui inclut une source lumineuse (2), un détecteur (36) et un système de polarisation optique (6, 38) permettant de réaliser des images vidéo des couches tissulaires biologiques superficielles (26, 32). Le dispositif se met en oeuvre par la réalisation d'une série de mesures prises à différentes orientations de la polarisation visant à produire une nouvelle image qui soit indépendante à la fois de la lumière (22) réfléchie par la surface (12) d'un échantillon tissulaire (14) et de la lumière (34) diffusée depuis les couches des tissus profonds (32).
