Abstract

In this paper, a study of the design of automotive communication lamps using microlens arrays (MLAs) was conducted. With the development of autonomous driving technology, automobiles need communication lamps to communicate with pedestrians. To reduce the size of the optical system and secure high light intensity, the communication lamp's optical system was designed using an MLA. In addition, to secure a clear image on inclined ground, the design was carried out considering the overlap method. After that, the improved performance was confirmed by comparing it to the MLA optical system before overlapping.

본 논문에서는 MLA (microlens array)를 이용한 자동차 커뮤니케이션 램프 설계 방안에 대한 연구를 진행하였다. 자율주행기술의 발전으로 보행자와 차량 간의 소통을 위한 커뮤니케이션 램프가 자동차에 필요하게 되었다. 광학계의 크기를 줄이고, 높은 광량을 확보하기 위해 MLA를 사용하여 커뮤니케이션 램프 광학계를 설계하였다. 또한, 기울어진 지면에서 선명한 image를 확보하기 위해 중첩방안을 고려하여 설계를 진행하였다. 이후 중첩 전 MLA 광학계와 성능 비교를 통해 향상된 성능을 확인하였다.
