	Numerical simulations for adaptive optics system (EI CONFERENCE) 会议论文 OAI收割 31st Chinese Control Conference, CCC 2012, July 25, 2012 - July 27, 2012, Hefei, China 作者: Wang X.-J. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 The simulation methods for the adaptive optics (AO) system are studied. Based on the global structure of the AO system the key principles for each module are first discussed systematically including the wave propagation principles wave-front representation coordinates transformation between the coordinates considered wave-front reconstruction algorithm and DM principles. The purpose of these discussions is to establish the theoretical foundations for the numerical simulations of the AO system. Then the simulation steps are described in detail and a series of numerical simulation results are given which validate the effectiveness of our simulation work. 2012 Chinese Assoc of Automati.

	Miniaturize photoelectric stable platform (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Computer Application and System Modeling, ICCASM 2010, October 22, 2010 - October 24, 2010, Shanxi, Taiyuan, China Xue W.-Q.; Wang Y.-Y.; Dai M. 收藏 \| 浏览/下载：79/0 \| 提交时间：2013/03/25 In order to reduce the size and weight of the gimbal in a traditional stable platform and correct the disadvantage in size of the payload the paper first improves the gimbal which is an important component of a stable photoelectric platform that also is an important factor in affecting the size and weight of a stability platform. In this paper a closed-form solution of 3-DOF manipulator is designed according mechanical arm design principles. This manipulator is formed by a three joint axes whose extended line is intersected at one point. A standard orthogonal coordinate system is set up for each rod in the manipulator. And then rotation transformation matrix expression is obtained. At last in this paper the manipulator arm-shaped method for solving solutions is description and also each parameter of the gimbal is calculated when the photoelectric detection devices at bottom reach the expected position. Test results show that the photoelectric stability platform with gimbal we designed is smaller lighter and simpler than that traditional. Also the packaging and size of the photoelectric will not be affected with this open structure. 2010 IEEE.
	Non-contact and on-line cone diameter measuring based on high speed linear CCD (EI CONFERENCE) 会议论文 OAI收割 2nd International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, November 2, 2005 - November 5, 2005, Zian, China Guohui Z.; Jianhua W. 收藏 \| 浏览/下载：38/0 \| 提交时间：2013/03/25 The remarkable improvement of sensing and processing hardware performance makes the non-contact on-line high accuracy and high speed measuring possible by means of linear CCD. The goal of this pager is to describe the key questions on designing the cone diameter detecting system by linear CCD. This paper first describes the detecting scheme. In particular the factors affecting accuracy such as resolution voltage difference between neighbor pixels detecting rate and so on are analyzed and the quantitative estimation equations are provided. CCD takes on the photoelectric translation and measuring component double functions so the waveform of CCD output signal and the affecting factors merit deep discussion. On the basis of discussion several principles that can be used to improve the boundary recognition accuracy are presented.
