Abstract

An infrared imaging method is proposed in which direct measurement of the spectral response of CCD sensors can be achieved through digital image processing. This method allows for a simple and economic method to detect the spectral sensitivity of commercialized CCD sensors. The key components of the apparatus are a monochromator, CCD-sample supporter and a personal computer equipped with a digital image processing systems. Tentative experimentation conducted on the commercialized CCD camera has resulted in a fairly consistent agreement with the theoretical model.

디지털 영상처리를 이용해 CCD 센서의 스펙트럼 응답특성을 직접 측정할 수 있는 적외선 영상기법을 제안하고 있다. 이 방법은 쉽고 경제적인 방법으로 상용 CCD 센서의 스펙트럼 감도를 검출할 수 있도록 한다. 본 장치의 핵심 부품은 단색광원기, CCD 지지대, 디지털 영상처리 시스템이 내장된 컴퓨터이다. 방법의 타당성을 증명하기 위해 상용 CCD 카메라에 대해 시험적으로 행한 실험은 이론적인 모델과 잘 일치함을 보여 주었다.
