The form of composite triangular and rectangular and the combination of open and closed back was explored in the lightweight design. A new kinematic mount and flexible structure in axis is used to hold the mirror around the lateral surface. The structure can minimize distortions induced by coefficient of thermal expansion mismatch among the materials. This eliminates the bending of the integral mount under the weight of the mirror. Optical performance of the mirror was analyzed under gravity load and temperature load using finite element method. Predicted surface figure error based on the removal of bias  tilt and power was calculated using an in-house Matlab script for mirrors. The pointing mirror assembly was tested using open loop servo control. And the surface figure was checked using interferometer. Surface figure accuracy is better than 1/30 ( 632.8nm  rms). The results show that the kinematic mount induces minimal figure error on the optical surface. 2011 IEEE.   Singularities of symplectic and Lagrangian mean curvature flows 期刊论文  OAI收割 FRONTIERS OF MATHEMATICS IN CHINA, 2009, 卷号: 4, 期号: 2, 页码: 283-296 作者:  Han, Xiaoli;  Li, Jiayu   |  收藏  |  浏览/下载：17/0  |  提交时间：2018/07/30 Symplectic surface  holomorphic curve  Lagrangian surface  minimal Lagrangian surface  mean curvature flow   Minimal consistent subset for hyper surface classification method 期刊论文  iSwitch采集 International journal of pattern recognition and artificial intelligence, 2008, 卷号: 22, 期号: 1, 页码: 95-108 作者:  He, Qing;  Zhao, Xiu-Rong;  Shi, Zhong-Zhi 收藏  |  浏览/下载：33/0  |  提交时间：2019/05/10 Hyper surface classification (hsc)  Minimal consistent subset (mcs)  Sampling  Generalization ability   Minimal consistent subset for Hyper Surface Classification method 期刊论文  OAI收割 INTERNATIONAL JOURNAL OF PATTERN RECOGNITION AND ARTIFICIAL INTELLIGENCE, 2008, 卷号: 22, 期号: 1, 页码: 95-108 作者:  He, Qing;  Zhao, Xiu-Rong;  Shi, Zhong-Zhi   |  收藏  |  浏览/下载：14/0  |  提交时间：2019/12/16 Hyper Surface Classification (HSC)  Minimal Consistent Subset (MCS)  sampling  generalization ability   G(2) surface modeling using minimal mean-curvature-variation flow 期刊论文  OAI收割 COMPUTER-AIDED DESIGN, 2007, 卷号: 39, 期号: 5, 页码: 342-351 作者:  Xu, Guoliang;  Zhang, Qin   |  收藏  |  浏览/下载：20/0  |  提交时间：2018/07/30 Euler-Lagrange equation  minimal mean-curvature-variation flow  energy functional  discretization  surface modeling   Minimal mean-curvature-variation surfaces and their applications in surface modeling 期刊论文  OAI收割 GEOMETRIC MODELING AND PROCESSING - GMP 2006, PROCEEDINGS, 2006, 卷号: 4077, 页码: 357-370 作者:  Xu, Guoliang;  Zhang, Qin   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/07/30 Euler-Lagrange equation  minimal mean-curvature-variation flow  energy functional  discretization  surface modeling
