Abstract

In order to study the influence of sampled response on the image generated by staring photoelectric imaging system, this paper analyzes the sampled response process and sampled response function, defines the comprehensive resolution and canonical image, and discusses the effect of comprehensive resolution on transfer responses, in-band and out-of-band spurious responses from one-dimensional and two-dimensional perspectives, respectively. The results show that: as the comprehensive resolution increases, the image resolution and sharpness decrease due to the reduction of high frequency components in the transfer response and the image aliasing decreases due to the reduction of in-band spurious responses. When the comprehensive resolution is equal to 1.5, a balance is provided between image resolution and image aliasing. These conclusions have certain reference value in the modeling, testing and evaluation of staring photoelectric imaging system.
