For making complex optical system meet the design requirement  such as the space camera used in remote sensing and UVX lithophotography  especially for off-axis all-reflecting optical system  alignment technology is so necessary. In this paper  a method is presented. Based on the ideas of linearity instead of non-linearity and difference quotient instead of differential quotient  a mathematical model for computer-aided alignment is proposed. This model included the characteristics of the optical system  wavefront difference of its exit pupil and its misalignment of the misaligned optical system. Then comparing self-compiled software with alignment package of CODE V  as a result  this self-compiled software is much more valid than alignment package of CODE V. For a large aperture  long focal length and off-axis three-mirror optical system  computer-aided alignment is successful. Finally  the wavefront error of the middle field is 0.094 waves RMS and the wavefront error of +0.7 field is 0.106 waves RMS and the wavefront error of -0.7 field is 0.125 waves RMS at =632.8nm are obtained.
