Abstract

TDI-CCD can improve the sensitivity of space camera without any degradation of spatial resolution which is widely used in aerospace imaging devices. The article describes the basic working principle and application characteristics of TDI-CCD devices, analyses the composition of TDI-CCD imaging noise, and propose a new method to analyze TDI-CCD imaging noise with statistical probability distribution. In order to estimate the distribution of gray values affect by noise we introduced the concept of skewness and kurtosis. We design an experiment using constant illumination light source, take image with TDI-CCD working at different stage such as stage 16, stage 32, stage 48, stage 64 and stage 96, analyse the characteristics of image noise with the method we proposed, experimental results show that the gray values approximately meet normal distribution in large sample cases.
