	Study on the calculation and application for asphericity of rectangle off-axis aspherics (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: Xuan B.; Song S.-M.; Xie J.-J.; Xie J.-J.; Zhang H. 收藏 \| 浏览/下载：68/0 \| 提交时间：2013/03/25 Asphericity which affects the manufacturing process and the grinding quantity is an important parameter of optical aspherics. In this paper the approximation the least square fitting wavefront aberration sag methods are given for the calculation of optical asphericity. The effects of different definitions of optical asphericity are analysed to optimize the process of manufacture. A sag method is presented to solve the best-fit sphere and asphericity for an off-aixs aspheric mirror with a rectangle aperture of 180mm145mm and polishing quantity and distribution plots are given. The optical manufacturing and testing technology for different choices of best-fit spheres and asphericity are described and analyzed. Therefore proper definition of optical asphericity which is useful to manufacturing is very important for optical fabrication and test. 2009 SPIE.
	Based on Householder transform of the Zernike polynomial wave front fitting method to solve active optics correction force (EI CONFERENCE) 会议论文 OAI收割 Infrared Materials, Devices, and Applications, November 12, 2007 - November 15, 2007, Beijing, China 作者: Wu X.-X. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 Corrective force solving is a critical technology of the active optics. A method to solve active optics corrective force is introduced which is based on Householder transform of Zernike polynomial wave front fitting this method is different from the traditional least square method and Gram-Schmid orthogonal method because it does not bring ill-conditioned polynomial without constructing normal equation so it can avoid calculation error wave front fitting is precision. Based on the coefficient of the Zernike polynomial and the response function of the each actuator the stiffness matrix of the primary mirror is built and then adopting the damp least square method to calculate corrective force. Based on this method cp400m test mirror is simulated many times the calculation result approve: if the Householder transform is adopted wave front fitting is precision the result is stabilization and corrective effectiveness is better.
