Based on the global structure of the AO system  the key principles for each module are first discussed systematically  including the wave propagation principles  wave-front representation  coordinates transformation between the coordinates considered  wave-front reconstruction algorithm and DM principles. The purpose of these discussions is to establish the theoretical foundations for the numerical simulations of the AO system. Then the simulation steps are described in detail and a series of numerical simulation results are given which validate the effectiveness of our simulation work. 2012 Chinese Assoc of Automati.   Test of an off-axis asphere by subaperture stitching interferometry (EI CONFERENCE) 会议论文 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, November 19, 2008 - November 21, 2008, Chengdu, China Wang X.-K.; Zheng L.-G.; Zhang B.-Z.; Li R.-G.; Di F.; Deng W.-J.; Xu W.; Feng Z.; Zhang Z.-Y.; Zhang X.-J. 收藏  |  浏览/下载：45/0  |  提交时间：2013/03/25 A new method combined subaperture stitching with interferometry(SSI) is introduced. It can test large and off-axis aspheric surfaces without the aid of other null optics. In this paper the basic principle and theory of the technique are analyzed. The synthetical optimization stitching model and effective stitching algorithm are established based on homogeneous coordinates transformation and simultaneous least-squares method. The software of SSI is devised and the prototype for testing of large aspheres by SSI is designed and developed. An off-axis asphere with the aperture of 376mm188mm is tested by this method. For comparison and validation  and the difference of PV and RMS error between them is 0.047 e and 0.006 e  the asphere is also tested by null compensation.The synthesized surface profile is consistent to that ofthe entire surface from null test  respectively. So it provides another quantitative measurement for testing large aspheric surfaces and off-axis aspheres besides null-compensation. 2009 SPIE.
