Title (EN) OPTICAL CROSS TALK MITIGATION FOR OPTICAL DEVICE
(FR) ATTÉNUATION DE DIAPHONIE OPTIQUE POUR DISPOSITIF OPTIQUE
Abstract:
(EN) A system and method are disclosed for reducing light from one or more light sources from entering into a light sensor by reflection off of a visor and/or waveguiding within the visor. In embodiments, a shroud may be provided around the light sensor to block light reflected off of the visor from entering the light sensor. In embodiments, pattern of one or more grooves may be formed in the visor to block light waveguided within the visor from entering the light sensor.
(FR) L'invention concerne un système et un procédé permettant de réduire l'entrée de la lumière provenant d'une ou plusieurs sources de lumière dans un capteur de lumière par la réflexion sur un masque et/ou le guidage d'onde dans le masque. Dans des modes de réalisation, un écran peut être présent autour du capteur de lumière pour bloquer l'entrée de la lumière réfléchie sur le masque dans le capteur de lumière. Dans des modes de réalisation, un motif à une ou plusieurs rainures peut être formé dans le masque pour bloquer l'entrée de la lumière guidée par guidage d'onde dans le masque dans le capteur de lumière.
