Abstract

In this paper, the optical properties of a miniature telecentric camera are studied analytically and experimentally. By means of optical properties, the luminous intensity of retro-reflection of a miniature telecentric optical system is investigated. First, from a simulation the theoretical value of the coefficient of luminous intensity of retro-reflection of a miniature telecentric system is estimated. Second, a miniature telecentric camera device is designed, and the value of the coefficient of luminous intensity of retro-reflection of the actual device is measured through experiment. From simulation and experiment, we found that both the estimated and observed values of the coefficient of luminous intensity of retro-reflection range from 0.002 to $0.03m^2/sr$ (P384200CPH: $0.0042-0.018m^2/sr$, P285200CPH: $0.0045-0.0297m^2/sr$, P321450S: $0.0021-0.00963m^2/sr$) at 1.4 to 4.9 arcminute. The results prove the significance of the mechanisms used to design the miniature telecentric camera, and the experimental method. Accordingly, with these significant results, this study contributes to the development of theory and practice in optical engineering science.

이 논문에서는 소형센트릭 카메라의 광학적 특성이 분석적, 실험적으로 연구되었다. 광학적 특성으로 소형센트릭광학계의 재귀반사 광도계수가 조사되었다. 우선, 시뮬레이션을 통해서, 이론적 재귀반사광도계수 값을 측정하였다. 두번째로, 소형센트릭 카메라 장치를 디자인 하였으며, 이후 실험을 통해 실제 장치의 재귀반사광고계수를 측정하였다. 시뮬레이션과 시험을 통해, 재귀반사광도계수의 측정치 및 실험치 모두가 (P384200CPH: $0,0042m^2/sr{\sim}0,018m^2/sr$, P285200CPH: $0,0045m^2/sr{\sim}0,0297m^2/sr$, P321450S: $0,0021m^2/sr{\sim}0,00963m^2/sr$) 1.4 ~ 4.9의 분각에서 $0,002{\sim}0,03m^2/sr$의 범위에 있음을 발견하였다. 이 결과는, 실제 장비를 구상하는데 사용된 메커니즘과 실험방법의 중요성(유효성)을 증명한다. 이에따라, 이 유효한 결과를 통해서, 이 연구는 광학공학의 이론과 실제의 발전에 기여하였다.
