	In situ long trace profiler for measurement of Wolter type-I mirror (EI CONFERENCE) 会议论文 OAI收割 Advances in Metrology for X-Ray and EUV Optics III, August 1, 2010 - August 2, 2010, San Diego, CA, United states 作者: Chen B.; Chen B. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 The surface profile of Wolter type-I mirror has a great impact on the performance of Solar X-ray Telescope. According to the existing fabrication instrument and experimental conditions in our lab an in situ Long Trace Profiler is developed and set up on the fabrication instrument in order to measure the surface profile of Wolter mirror in real time during fabrication process. Its working mechanism structural parameters and data processing algorithm are investigated. The prototype calibrated by a standard plane mirror is used to measure a sample of Wolter type-I mirror. The results show that our prototype can achieve an accuracy of 2.6rad rms for slope error with a stability of 1.33rad during the whole measurement period. This can meet further fabrication requirements. 2010 Copyright SPIE - The International Society for Optical Engineering.
	Test of an off-axis asphere by subaperture stitching interferometry (EI CONFERENCE) 会议论文 OAI收割 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 作者: Zheng L.-G.; Zhang X.-J.; Zhang Z.-Y.; Zhang Z.-Y.; Deng W.-J. 收藏 \| 浏览/下载：54/0 \| 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.
