Abstract

A procedure and method for the MDI(Minimum Detectable Irradiance) measurement of an infrared point source detection system is described in detail and its experimental result is analyzed. The proposed measurement method for MDI can be realized with a collimator in the laboratory environment. In addition, an estimation method of the maximum detection range of the infrared point source detection system is introduced and its performed result is shown.

외선 점광원 탐지장비의 탐지성능 예측을 위한 최소탐지조도(MDI)를 측정하고 실험결과를 제시하였다. 최소탐지조도 측정은 시준기를 이용하여 실험실 환경에서 수행할 수 있는 방법으로 구현하였으며 측정에 따르는 시험조건 및 절차를 상세히 기술하였다. 또한 최소탐지조도 측정 결과를 이용하여 분석한 적외선 탐지장비의 최대탐지거리 예측결과를 제시하였다.
