摘　　要：光学拼接是扩大CCD相机视场的有效方法,其关键技术为拼接精度的设计计算和正确评价。为了对光学拼接的工艺性进行有效评价,指导CCD光学拼接的设计,以光学调制传递函数(MTF)为其评价函数,分别对光学拼接的搭接误差、直线性误差、共面性误差对时间延迟积分电荷耦合器件(TDI-CCD)相机光学传递函数的影响进行了理论分析,给出了各种光学拼接误差对光学系统传递函数的调制方程,为光学拼接技术的精度评价提供了理论依据,能够有效指导光学设备焦平面组件的工程设计。The optical assembly of CCD is an effective technology for broadening view field of camera, and its key way is the right design and assessment of assembly precision. For evaluating optical assembly precision and instructing the design of CCD optical assembpy, MTF is used for its evaluting founction, and analysing overlap error, linear error and coplane error influence on TDI-CCD camera＇s modulation transfer function （MTF）. The modulating equation of assembly errors on MTF is given, and supply theoretical reason for the assessment of optical assembly precision,and guide the engineering design of optical equipent＇s focal plane.
