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.   Study of 316L stainless steel coronary stent high vacuum heat treatment (EI CONFERENCE) 会议论文  OAI收割 2009 IEEE International Conference on Mechatronics and Automation, ICMA 2009, August 9, 2009 - August 12, 2009, Changchun, China 作者:  Wang J.-L.;  Wang J.-L. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 Establish the high vaccum heat treatment platform for high vacuum heat treatment of 316L stainless steel coronary stent  by analysis the influence of heating-up temperature and holding time  fix the art of high vaccum heat treatment through optimizing series parameters  draw the conclusion that we may inlet auxiliary gas and add wire netting to achieve bright heat treatment sample. 2009 IEEE.
