Abstract

Un appareil (10) d'imagerie par contraste de tavelures comprend deux polariseurs (7, 8) qui sont orientés orthogonalement l'un par rapport à l'autre, et qui sont disposés respectivement sur un trajet d'un rayonnement d'éclairage (F1) et sur un trajet d'un rayonnement rétrodiffusé (RR) provenant d'une cible (T) observée. Les polariseurs augmentent une contribution relative dans chaque image saisie, d'une partie du rayonnement qui subit des diffusions multiples dans la cible, à une certaine profondeur sous une surface de ladite cible. Un tel appareil est particulièrement adapté pour visualiser des inhomogénéités de vascularisation, et notamment des inhomogénéités de vascularisation à l'échelle micrométrique, dans un tissu biologique en utilisant un procédé d'observation LASCA.
