Abstract

Abstract: In terms of optical detector construction and characteristic, the modulation transfer function (MTF) was selected as the system performance index, and MTF models were established. The influences of pixel size on the optical detector performance were analyzed by simulation. The results show that as the pixel size decreases, the image sensor MTF increases, while the optical system, defocus, image motion MTF decreases.

Key words: Pixel size, Image sensor, Modulation transfer function, Optical detector, Performance index, Space remote sensing
