Abstract

The staring imaging technique is one of the main research directions in the field of the opto-electronic imaging. Therefore, the analysis of imaging performance of staring imaging system is a key issue in the research work. It includes the following parameters, MTF, SNR, MRTD, distortion etc, among which MTF is one of the most important parameters in evaluating the performance of the detector and the system. In this paper, we report a thorough analysis on the characteristics of MTF from the spatial and frequency spectrum. This Fourier transform based analysis was performed on the dynamic imaging characteristics of staring imaging system. Furthermore, abundant experiments were made on the measurement of MTF of visible CCD and IRFPA, thereby the results was obtained for the performance analyzing of staring imaging system.
