Title (EN) LIGHT DETECTION AND RANGING DEVICE
(FR) DISPOSITIF DE DÉTECTION DE LUMIÈRE ET DE TÉLÉMÉTRIE
(KO) 광파 탐지 및 거리 측정 장치
Abstract:
(EN) A light detection and ranging device according to one embodiment comprises: a light transmitting unit for emitting a plurality of beams in different directions from each other; and a light receiving unit for allowing rear light beams, which return by being reflected after the emitted beams hit an object, to be incident at angles different from each other, and measuring information on the object by using the plurality of incident rear light beams, wherein the light transmitting unit comprises: at least one light source for emitting light; a beam splitting unit for splitting the light emitted from the at least one light source into a first beam and a second beam; and a beam steering unit for dividing, into a plurality of third beams, the second beam split by the beam splitting unit such that the third beams are emitted in directions different from each other, wherein the plurality of beams emitted from the light transmitting unit include the first beam and the plurality of third beams.
(FR) L'invention concerne un dispositif de détection de lumière et de télémétrie qui, selon un mode de réalisation, comprend : une unité d'émission de lumière pour émettre une pluralité de faisceaux dans des directions différentes les unes des autres; et une unité de réception de lumière pour permettre à des faisceaux de lumière arrière, qui reviennent en étant réfléchis après que les faisceaux émis heurtent un objet, d'être incidents à des angles différents les uns des autres, et pour mesurer des informations sur l'objet en utilisant la pluralité de faisceaux de lumière arrière incidents, l'unité d'émission de lumière comprenant : au moins une source de lumière pour émettre de la lumière; une unité de division de faisceau pour diviser la lumière émise par ladite source de lumière en un premier faisceau et un deuxième faisceau; et une unité d'orientation de faisceau pour diviser, en une pluralité de troisièmes faisceaux, le deuxième faisceau divisé par l'unité de division de faisceau, de telle sorte que les troisièmes faisceaux sont émis dans des directions différentes les unes des autres, la pluralité de faisceaux émis par l'unité d'émission de lumière comprenant le premier faisceau et la pluralité de troisièmes faisceaux.
(KO) 실시 예에 의한 광파 탐지 및 거리 측정 장치는, 복수의 빔을 서로 다른 방향으로 방출하는 광 전송부 및 방출된 빔이 대상에 부딪힌 후 반사되어 돌아오는 후방 광을 서로 다른 각도에서 입사하고, 입사된 복수의 후방 광을 이용하여 대상에 대한 정보를 측정하는 광 수신부를 포함하고, 광 전송부는 광을 방출하는 적어도 하나의 광원과, 적어도 하나의 광원에서 방출된 광을 제1 빔과 제2 빔으로 분할하는 빔 분할부 및 빔 분할부에서 분할된 제2 빔을 복수의 제3 빔으로 나누어 서로 다른 방향으로 방출하는 빔 스티어링부를 포함하고, 광 전송부로부터 방출되는 복수의 빔은 제1 빔과 기 복수의 제3 빔을 포함한다.
