Abstract

L'invention concerne un système d'imagerie, comprenant une plaque de recouvrement transmettant la lumière, un capteur d'image et un élément optique diffractif, le capteur d'image étant agencé au-dessous de la plaque de recouvrement transmettant la lumière ; et l'élément optique diffractif est agencé entre la plaque de recouvrement transmettant la lumière et le capteur d'image. Après pénétration à travers la plaque de recouvrement transmettant la lumière, la lumière provenant d'un objet à mesurer est diffractée par l'élément optique diffractif de façon à être imagée sur le capteur d'image.
