The six degrees of freedom nonlinear model simulation result shows that: the control parameters designed are reasonable  the simulation profile is fully consistent with the setting profile  the control effect of pitch angle loop and altitude loop meets with the indices requirements  the method is mature and reliable  easy to realize in engineering.

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.   CONSTRAINING DARK ENERGY FROM THE SPLITTING ANGLE STATISTIC OF STRONG GRAVITATIONAL LENSES 期刊论文  OAI收割 ASTROPHYSICAL JOURNAL, 2009, 卷号: 694, 期号: 2, 页码: 1402-1412 作者:  Zhang, Qing-Jun;  Cheng, Ling-Mei;  Wu, Yue-Liang;  Zhang, QJ , Chinese Acad Sci, Inst Theoret Phys, Kavli Inst Theoret Phys China, Beijing 100080, Peoples R China   |  收藏  |  浏览/下载：42/0  |  提交时间：2012/08/02 Universal Density Profile  All-sky Survey  Cosmological Consequences  Matter Halos  Models  Component  Parameters  Supernovae  Evolution  Abundance   Double-swing method used for polishing off-axis aspherical mirrors (EI CONFERENCE) 会议论文  OAI收割 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Advanced Optical Manufacturing Technologies, November 19, 2008 - November 21, 2008, Chengdu, China 作者:  Chen Y.;  Song S.-M.;  Xuan B.;  Wang P.;  Li J.-F. 收藏  |  浏览/下载：68/0  |  提交时间：2013/03/25 Based on the characteristics of off-axis aspherical surface  the comparison of simulation effects under different parameters is made. In order to achieve optimal parameters  a new method used for polishing off-axis aspherical mirrors-Double-Swing Method (DSM) is proposed in this paper  a high order off-axis rectangle aspherical mirror has been polished by DSM. The final result of profile measurements of 12nm  and the polishing mechanism of DSM is introduced. The mathematical model of the DSM with steady movement state is established.The movement of this mathematical model is simulated in a programming language  RMS is achieved. The result indicates that the method is of practice and has even higher working efficiency and precision. 2009 SPIE.
