摘　　要：TDICCD器件和亚像元成像技术都是实现相机小型化的有效途经 ,TDICCD器件和亚像元成像技术结合应用于小相对孔径光学系统具有重要的应用价值 就成像系统需要满足Nyquist频率处静态传函≥ 0 .2条件对系统进行了分析、讨论 。Both TDI CCD and sub-pixel imaging technique are effective methods to minimize the Camera, and it′s of practical value to combine these two techniques together to implement a smaller relative aperture optical system A systematic analysis and discussion is made under the rule that the value of static Modulation Transfer Function at Nyquist frequency be equal to or more than 0.2,a suggestion of introducing SNR to imaging system design is proposed.
