A selective light transmitting and receiving system for the reduction of glare and unwanted light. The selective light system includes a light source, a first polarized filter adapted to polarize light emanating from the light source in a first polarization orientation, a second polarized filter adapted to perform polarized filtering of received light in a second polarization orientation, and a light receiving device adapted to receive the filtered light. The selective light system may be incorporated into a vehicle system, a roadway system, a camera or video system, a microscope system, a night vision device, a hard hat lighting system, and a stage lighting system.

L'invention concerne un système d'émission et de réception sélectives de lumière permettant de réduire l'éblouissement et la lumière non désirée. Ce système de lumière sélectif comprend une source de lumière, un premier filtre polarisé conçu pour polariser la lumière émanant de la source de lumière dans une première direction de polarisation, un deuxième filtre polarisé conçu pour effectuer un filtrage polarisé de la lumière reçue dans une deuxième direction de polarisation, et un dispositif récepteur de lumière conçu pour recevoir la lumière filtrée. Le système de lumière sélectif selon l'invention peut être incorporé dans un système de véhicule, un système de route, un système de caméra ou vidéo, un système de microscope, un dispositif de vision nocturne, un système d'éclairage de casque de protection et un système d'éclairage de scène.
