Title (EN) METHOD AND APPARATUS FOR INTENSITY CONTROL OF MULTIPLE LIGHT SOURCES USING SOURCE TIMING
(FR) PROCÉDÉ ET APPAREIL DE COMMANDE DE L'INTENSITÉ DE PLUSIEURS SOURCES LUMINEUSES METTANT EN OEUVRE UNE SYNCHRONISATION DES SOURCES
Abstract: front page image
(EN)A method and apparatus for controlling light intensity from two or more light sources (202, 204, 206). A timing scheme is used to modulate the light sources. Light from the light sources is combined to form a beam (210) and a photo-sensor (216, 218) senses the beam. In a time interval when only one of the light sources is activated, the signal from the photo-sensor is monitored and used in a feedback control circuit (602) to control the active light source (202, 204, or 206).
(FR)L'invention concerne un procédé et un appareil permettant de commander l'intensité lumineuse provenant d'au moins deux sources lumineuses (202, 204, 206). Un schéma de synchronisation est utilisé pour moduler les sources lumineuses. Un rayonnement provenant des sources lumineuses est combiné de manière à former un faisceau (210) et un photo-capteur (216, 218) détecte le faisceau. Dans un intervalle temporel pendant lequel uniquement une des sources lumineuses est activée, le signal provenant du photo-capteur est surveillé et utilisé dans un circuit de commande de rétroaction (602), afin de commander la source lumineuse active (202, 204 ou 206).
