Abstract:
(EN) The present invention relates to an integrated light transmission/reception optical system module and a scanning lidar having the same, the module simplifying an optical system structure and, at the same time, facilitating the alignment of optical systems since a light transmission optical system and a light reception optical system are integrated. According to the present invention, the integrated light transmission/reception optical system module comprises: a light reception lens receiving, by a light detection unit disposed at the rear thereof, light to be received, formed so as to face the center portion thereof from the circumference thereof, and having an optical path groove of which the front side is exposed; a light source for outputting a pulse laser along the optical path groove so as to allow the same to face the center portion of the light reception lens from the circumference thereof; and a light transmission mirror disposed in the optical path groove, and positioned on a path of the pulse laser so as to reflect, to the front, the pulse laser outputted from the light source.
(FR) La présente invention concerne un module de système optique d'émission/réception de lumière intégré et un Lidar à balayage comprenant celui-ci, ce module simplifiant une structure de système optique et, en même temps, facilitant l'alignement de systèmes optiques étant donné qu'un système optique de émission de lumière et un système optique de réception de lumière sont intégrés. Selon la présente invention, le module de système optique d'émission/réception de lumière intégré comprend : une lentille de réception de lumière recevant, par une unité de détection de lumière disposée à l'arrière de celle-ci, une lumière devant être reçue, formée de manière à faire face à la partie centrale de celle-ci à partir de la circonférence de celle-ci, et présentant une rainure de trajet optique dont le côté avant est exposé ; une source de lumière destinée à émettre un laser à impulsions le long de la rainure de trajet optique de façon à lui permettre de faire face à la partie centrale de la lentille de réception de lumière à partir de la circonférence de celle-ci ; et un miroir de transmission de lumière disposé dans la rainure de trajet optique, et positionné sur un trajet du laser à impulsions de façon à réfléchir, vers l'avant, le laser à impulsions émis par la source de lumière.
(KO) 본 발명은 송광 광학계와, 수광 광학계를 일체화시켜 광학계 구조를 단순화시킴과 동시에, 광학계 정렬이 용이한 송수광 일체형 광학계 모듈 및 이를 구비하는 스캐닝 라이다에 관한 것이다. 본 발명에 따른 송수광 일체형 광학계 모듈은 수광되는 광을 후방에 배치되는 광 검출부로 수광하고, 원주로부터 중심부를 향하도록 형성되며 전방이 노출된 광로홈이 형성된 수광 렌즈, 수광 렌즈의 원주로부터 중심부를 향하도록 광로홈을 따라 펄스 레이저를 출력하는 광원, 광로홈 내에 배치되며 펄스 레이저의 경로 상에 위치하여, 광원으로부터 출력되는 펄스 레이저를 전방으로 반사시키는 송광 미러를 포함한다.
