| 摘 要： | 通过对ＣＣＤ采样过程的分析，说明了输入信号与ＣＣＤ像元位相匹配对调制传递函数（ＭＴＦ）有影响。利用自制的ＭＴＦ测量装置，在两个像元长度范围内，测定了线阵ＣＣＤ的ＭＴＦ随输入信号与ＣＣＤ像元之间的位相而变化的情况，实验结果与理论结果吻合

| Abstract: | That the phase match between input signal and CCD pixel has influence on the measuring results of MTF is showed by the analysis of the CCD sampling process. The situation that MTF values of linear CCD array change with the phase of input signal is measured in the range of two pixels period. The experiment is done by using the apparatus made by themselves. The results accord with the theory results. |
