Abstract

LiDAR, a method of distance measurement using lasers, is used to confirm and use spatial distance information. The miniaturization of these products to increase the measurement coverage and improve the space utilization is essential. In this paper, we propose a new type of miniaturized optical structure that uses only holographic optical elements instead of the conventional method using lenses, reflectors, and diffractive elements as transmission optical parts. And through this, we confirmed that the range of measurable angle of view can be adjusted and miniaturized as needed.

공간상의 거리 정보 확인 및 이용에 레이저를 이용한 거리측정 방식인 LiDAR가 널리 활용되고 있다. 이 LiDAR에서 측정 범위의 확장과 공간 활용을 위한 소형화의 필요성이 명백하다. 본 논문에서는 렌즈와 반사경 및 회절소자를 송신 광학부로 사용하는 기존의 방식 대신에 홀로그램 광학 소자(holographic optical element)만으로 구성되는 새로운 형식의 소형 광학계를 제안하였다. 이를 통해 측정 가능한 화각의 범위를 필요에 따라 조절하고 소형화가 가능함을 확인하였다.
