The analysis of 3D noise indicates that the measurement is effective. Two MRC models of ICCD imaging system has been established based on system performance of energy and modulation transfer whose target is three-bar. One MRC model is under the condition of standard A lamp, and the other is under the condition of night photo-spectrum. Because the MRC models integrate sensitivity, noise, target spatial frequency, MTF and the performance of human eye all together, the MRC models can evaluate limit performance of photoelectric imaging system more roundly.
