Abstract

Abstract Translated from English Un dispositif optique au travers duquel la lumière est transmise à un dispositif de détection ou de mesure (12, 13 ou 14) possède un chemin optique dans lequel la lumière transmise de manière spéculaire peut passer pour tomber sur une zone prédéterminée (25) du dispositif de détection ou de mesure. La lumière diffusée est envoyée vers le dispositif mais tombe sur la surface de détection (24, 24a, 24b) sur une zone plus vaste que la zone prédéterminée (25). Afin d'améliorer la réponse relative du dispositif à la lumière diffusée, un filtre d'atténuation (33, 33a, 33b) est placé sur la zone prédéterminée (25) de la surface de détection. An optical device through which light is transmitted to a sensing or measuring device (12, 13 or 14) has an optical path through which specularly transmitted light can pass to fall on a predetermined area (25) of the device detection or measurement. The scattered light is sent to the device but falls on the detection surface (24, 24a, 24b) over an area larger than the predetermined area (25). In order to improve the relative response of the device to scattered light, an attenuation filter (33, 33a, 33b) is placed over the predetermined area (25) of the detection surface.
