| 摘 要： | 推导并用实验验证了光强与入射波前在单位像元面积里成近似线性关系，从而得到入射波前经CCD采样后的功率谱密度（PSD）公式.根据该公式，模拟分析了影响CCD采集系统的系统传递函数的各个因素：入射波前、CCD的填充因子及CCD的曝光时间，得出了他们与系统传递函数的定性关系，并且通过实验明确CCD曝光时间对高空间分辨率波前检测不确定度的影响，为高空间分辨率干涉设计提供了理论依据.

| Abstract: | It is deduced and verified by experiment that the relation between optical intensity and incidence wavefront is nearly linear in unit cell size. Therefore, the formula of PSD sampled by CCD is obtained. According to the formula, many factors affecting the system transfer function in the CCD capture system are simulated and conformed by experiment, such as the maximum spatial frequency of incidence wavefront, the PSD of incidence wavefront in high spatial frequency, the fill factor and the exposure time of CCD. Then some useful qualitative conclusions between these factors and the system transfer function are obtained. Furthermore, the qualitative relation between the exposure time of CCD and repeatability of high spatial resolution interferometric optical test is conformed by experiment. |
