Title (EN) DISTANCE MEASUREMENT DEVICE AND OPTICAL SCANNING DEVICE
(FR) DISPOSITIF DE MESURE DE DISTANCE ET DISPOSITIF DE BALAYAGE OPTIQUE
(JA) 測距装置及び光走査装置
Abstract:
(EN) The present invention has: a light source unit for emitting pulsed light; an optical scanning unit for scanning a predetermined region through use of the pulsed light, the optical scanning unit having an intersection point at which trajectories of the pulsed light intersect when an imaginary surface in the predetermined region is viewed; a distance measurement unit for receiving reflected light from an object irradiated by the pulsed light and measuring the distance to the object; and a control unit for controlling emission of the pulsed light to the intersection point on the basis of a predetermined condition for the reflected light.
(FR) La présente invention comprend : une unité de source de lumière permettant d'émettre une lumière pulsée ; une unité de balayage optique permettant de balayer une zone prédéterminée par l'utilisation de la lumière pulsée, l'unité de balayage optique présentant un point d'intersection au niveau duquel des trajectoires de la lumière pulsée se croisent lorsqu'une surface imaginaire dans la zone prédéterminée est visualisée ; une unité de mesure de distance permettant de recevoir la lumière réfléchie par un objet irradié par la lumière pulsée et de mesurer la distance par rapport à l'objet ; et une unité de commande permettant de commander l'émission de la lumière pulsée vers le point d'intersection en fonction d'une condition prédéterminée pour la lumière réfléchie.
(JA) パルス光を出射する光源部と、パルス光によって所定の領域を走査し、所定の領域内の仮想の面を見たときにパルス光の軌跡が交差する交差点を有する光走査部と、パルス光が照射された対象物からの反射光を受光して対象物までの距離を測定する測距部と、反射光についての所定の条件に基づいて、交差点へのパルス光の出射を制御する制御部と、を有する。
