CCD Aerial Camera Modulation Transfer Function Test and Analysis

Abstract

The modulation transfer function(MTF) is important measure of CCD camera imaging system performance index. In this paper, based on the MTF, on the basis of theoretical analysis based on the resolution of the target in the camera lens focal plane imaging position deviation between CCD camera and CCD pixels, modulation transfer function is analyzed, the influence of the mathematical model is established. And the CCD camera system at Nyquist frequency of the MTF was tested, the experimental results and the calculated results are basically consistent.
