More Information
Summary:The present invention relates to a lidar receiver module. More specifically, the present invention relates to a lidar receiver module that comprises four lenses including a first lens having positive refractive power, a second lens having negative refractive power, a third lens having negative refractive power, and a fourth lens having positive refractive power. It functions as an F-theta lens for focusing the reflected light of a laser beam reflected from an object at a position proportional to an incident angle of the reflected light. 본 발명은 라이다 수광부 모듈에 관한 것으로, 보다 구체적으로는 양의 굴절력을 지니는 제1 렌즈, 음의 굴절력을 지니는 제2 렌즈, 음의 굴절력을 지니는 제3 렌즈 및 양의 굴절력을 지니는 제 4렌즈를 포함하는 4개의 렌즈로 마련되어, 객체로부터 반사된 레이저 빔의 반사광이 입사될 때의 입사각과 비례하는 위치에 결상되게 하는 에프-세타(F-theta) 렌즈로 기능하는 라이다 수광부 모듈에 관한 것이다.
