Modulation Transfer Function Measurement of a Linear Charge Coupled Device Imager by Using a Knife-Edge Scanner
칼날주사방법에 의한 일차원 CCD의 MTF 측정
Abstract
The scanning type modulation transfer function (MTF) measurement system of linear charge coupled device (CCD) imagers is fabricated and the MTF of a linear CCD imager is tested. Measured MTF values are very sensitive to small angle knife-edge skew within 1 degree and show different results in several wavelengths. The MTF of the linear CCD imager is measured in different color temperatures of a tungsten filament lamp and the MTF uniformity of ti,t eel) pixels is tested.tested.
칼날주사방법을 이용한 CCD의 MTF 측정장치를 제작하고 일차원 CCD의 MTF특성을 측정하였다. 주사방향에 수직인 직선과 칼날이 이루는 각도에 따른 CCD MTF 측정값의 변화는
