针对超大型光学遥感器的系统检测问题，文章在常规方法的基础上提出了子孔径拼接检测法，即采用小口径自准直平面镜代替全口径自准直镜在光轴竖直状态下进行系统检测，通过子孔径拼接算法可以高精度地还原系统全口径的波前信息。文章对该方法的基本原理进行了分析和研究，完成了相关仿真实验，利用口径为1.8m的自准直平面镜对口径为3.2m的光学系统进行了子孔径拼接检测，检测结果验证了该方法的理论可行性。

AbstractTo achieve the test of super large optical remote sensor, a technology of sub-aperture stitching interferometry is proposed based on the theory of traditional method. This system test method substitutes the full aperture flat mirror with a small one, and its optic axis is vertical. Wavefront of the whole aperture can be restored by sub-aperture stitching algorithm with high precision. The basic principle and theory of this technology are studied, and a relative simulation experiment is completed, in which the aperture of optical remote sensor is 3.2m and the sub-aperture is 1.8m. The result proves that test of super large optical remote sensor by sub-aperture stitching interferometry technology is feasible theoretically.
