	Research on key technical issues of contact method for large diameter off-axis aspheric segments 会议论文 OAI收割 SPIE Vol.9912, Edinburgh, United Kingdom, 2016-6-26 作者: ZiBo Jiang; XinNan Li; YongJun Liang; Bo Li; BinBin Yu 收藏 \| 浏览/下载：44/0 \| 提交时间：2017/01/24 Stressed Mirror Annular Polishing Off-axis aspherical mirror Contact detection Error analysis Polynomials orthogonality
	Technology on fabrication of precise SiC aspherical mirror (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Materials and Products Manufacturing Technology, ICMPMT 2011, October 28, 2011 - October 30, 2011, Chengdu, China Zhang Z. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 This paper represents a technique to produce the large size optical aspherical mirror by using reaction-bonded silicon carbide to meet the material requirements of the space used mirrors based on the characters comparison of all types mirror material. Techniques are described in this paper including the bonding procedure of silicon carbide to form a mirror shape the CCOM technology for aspheric grinding polishing on a home-developed tool -FSGJ-2 and the aspheric profilometry. A specialized Offner Null lens is also developed to measure the aspherical mirror with laser interferometer. With the technology depicted in the paper a 502mm 298 mm off-axis SiC aspherical mirror is successfully made with a surface accuracy better than 1/50rms the final result meets the design requirement.

	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：51/0 \| 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.
