In this paper, a diffractive optical element was designed to create lighting patterns that satisfy the requirements of adaptive headlight systems for normal road mode, highway mode, and wet road mode, and this was rendered into a GDSII stream format file.To verify the effectiveness of the light distribution formed by the diffractive optical elements and the realization of white light, simulations based on Field Tracing and Ray Tracing were conducted, confirming the satisfaction of position and luminance requirements at the transformation beam measurement points. Based on this research, it is anticipated that the implementation of adaptive headlights would be possible, enabling the reproduction of luminance contrast and the creation of a simple-structured adaptive headlight system.

본 논문에서는 적응형 전조등 시스템 규정 중 일반도로 모드, 고속도로 모드, 젖은도로 모드를 만족하는 배광의 형성을 위한 회절 광학 소자를 설계하였으며, 이를 GDSII 스트림 형식의 파일로 도출하였다. 회절 광학 요소를 통해 형성된 배광의 유효성 및 백색광 구현 여부 확인을 위하여 각각 Field Tracing, Ray Tracing 기반의 시뮬레이션을 진행하여 변환빔 측정점에 대한 위치 요구사항 및 광도 요구사항의 만족을 확인하였다. 본 연구를 기반으로 적응형 전조등을 구현하는 경우, 광도의 대비 재현 및 단순한 구조의 적응형 전조등 시스템 구현이 가능할 것으로 예상된다.
