Abstract

The applications for retro-reflectors, with their unique reflection characteristics, have been expanding, to include venetian blind slats, displays, traffic safety mark, etc. We propose expandable structures of inclined corner cube retro-reflectors and analyze their corresponding reflection characteristics. Various traffic safety structures with retro-reflectors may be designed more quantitatively using the chart of characteristics we have presented.

재귀 반사체(Retro Reflector)는 그 반사특성을 살려 베네치안 블라인드 슬랏, 디스플레이, 그리고 교통 안전 분야 등에서 활용 영역이 넓어져 가고 있다. 재귀 반사율 분포를 조절할 수 있는 코너 큐브 재귀 반사체를 정의하고, 입사각도에 따라 그 재귀반사광의 특성을 분석하여 교통 안전 분야에 적용하고자 하였다. 특성 분석 결과를 용이하게 파악할 수 있도록 시각화한 특성 도표를 고안하였으며, 이를 이용하여 다양한 교통 안전 분야의 재귀 반사 시트를 정량적으로 설계할 수 있음을 보였다.
