摘要	The variation of the wavefront aberrations of a Three-mirror Anastigmat(TMA) space camera under gravity was analyzed by integrated analysis method and the analytical accuracy was discussed. The basic process and key technology of the integrated analysis method were introduced, two kinds of surface distortion conversion interface algorithm (ZERNIKE polynomial fitting method and shape function interpolation method) were compared. Then, the principles of two kinds of shape functions were introduced, and the interface file of the optical element surface distortion was obtained by the area coordinate method. Finally, the variations of wavefront aberrations in gravity load were tested after the camera alignment was completed. Test results show that the variations of the wavefront aberrations of the three fields of view are respectively: 0.0298(-1), 0.0194(0), and 0.0523(+1), which are agreement with that of the analysis results. The errors of the analysis results of the three fields of view are respectively 0.0024(-1), -0.0009(0), 0.007(+1), all less than 0.01, meet the requirements of engineering and verify the correction of the integrated analysis method. Meanwhile, the quantitative effects of each factor on the system wavefront aberrations were obtained by the integrated analysis method. On the basis of the optimization design with the integrated analysis method, the influences of gravity on wavefront aberrations of the three fields of view of the space camera is significantly improved. 2016, Science Press.
