초록
홀로그래피 광학소자는 투명하고 얇은 필름 또는 플라스틱 형태로 다양한 기능을 포함할 수 있는 장점을 갖고 있어 광학제품,통신 및 디스플레이 분야에서 다양한 연구 개발이 진행되고 있다. 본 논문에서는 홀로그래피 광학소자의 원리 및 특성, 이를활용한 회절 광학소자, 홀로그래픽 투영 스크린, HMD 등 응용시스템에 대해 소개한다. 앞으로 홀로그래피 광학소자가 좀 더보편화되고 활용가치를 높이기 위해 풀어야 할 당면과제에 대해 설명한다.
Abstract
Holographic optical elements (HOEs) provide systems of thin-film optics that could include a variety of functions and havemany advantages as optical devices in various research fields. Research and developments based on the use of HOEs in the fieldsof communications and displays are in progress. This paper introduces the properties of HOEs and their applications in diffractiveoptical elements (DOEs), holographic projection screens, and head-mounted displays (HMDs). For widespread use of HOEtechnology in these various applications some challenges need to be solved, as discussed in this paper.
