According to the theory of linear filter and imaging characteristics of the whole optoelectronic imaging system are calculated and analyzed with the transfer function theory. Based on the filter theory of imaging processes and the deduced mathematics model of the image tube's dynamic transfer function, the dynamic imaging processes of an image tube are simulated numerically. The simulated results of dynamic imaging processes are given in images. It is proved to be feasible that the imaging process of an optoelectronic imaging system can be simulated by computer numerical simulation and the dynamic model of image tube thus obtained can simulate the dynamic imaging properly.
