In this paper  several kinds of multi-CMOS station mode are introduced. Fundamental principles and classification of station mode directly affect on measurement parameters of system. No matter what mode is designed  the ultimate goal is to extend Effective Viewing Field (EVF)  increase capture ratio of objects and increase measurement precision. Station mode introduced in this paper is made of CMOS cameras  because of low cost  high speed frame frequency and low power consumption  CMOS cameras were putted near from object tested. So sequences of image are legible  which are convenient for analysis of three dimensional(3D) attitude. 2010 IEEE.   Astrodynamical Space Test of Relativity Using Optical Devices I (ASTROD I)-A class-M fundamental physics mission proposal for Cosmic Vision 2015-2025 期刊论文  OAI收割 EXPERIMENTAL ASTRONOMY, 2009, 卷号: 23, 期号: 2, 页码: 491-527 作者:  Appourchaux, Thierry;  Burston, Raymond;  Chen, Yanbei;  Cruise, Michael;  Dittus, Hansjoerg 收藏  |  浏览/下载：44/0  |  提交时间：2011/12/08 Probing the fundamental laws of spacetime  Exploring the microscopic origin of gravity  Testing relativistic gravity  Mapping solar-system gravity  Solar g-mode detection  Gravitational-wave detection  ASTROD  ASTROD I   Design guidelines and characteristics of beam-shaping microstructure optical fibers 期刊论文  OAI收割 opt. commun., 2006, 卷号: 259, 期号: 2, 页码: 636, 639 Lu XQ; Zhou QL; 邱建荣; 朱从善; 范滇元 收藏  |  浏览/下载：1378/294  |  提交时间：2009/09/18 beam shaping  flat-top fundamental mode  microstructure optical fibers   Noise characteristic of laser diode pumped orange-yellow solid-state laser by intracavity sum-frequency of KTP Phase matching II (EI CONFERENCE) 会议论文  OAI收割 ICO20: Lasers and Laser Technologies, August 21, 2005 - August 26, 2005, Changchun, China Tan H.; Gao L. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 The laser diode pumped Nd: YVO4 orange-yellow laser has been presented in this paper. The fundamental wavelengths of 1064nm and 1342nm oscillate simultaneous to generate the 593.5nm wavelength by intracavity sumfrequency of KTP nonlinear crystal phase matching II. The noise characteristic of laser output has been measured and analyzed in different pumping power. The relations between the amplitude noise of sum-frequency output and the longitudinal mode of fundamental frequency have been researched. The results show that the sum-frequency output is low noise if the one of fundamental wavelengths is single longitudinal mode. The experiments show that amplitude noise of intracavity sum-frequency laser is lower than that of intracavity doubled frequency laser with the same structure.   Research on LD-Pumped dual wavelength Nd:YAG Laser with high beam quality for machining (EI CONFERENCE) 会议论文  OAI收割 ICO20: Lasers and Laser Technologies, August 21, 2005 - August 26, 2005, Changchun, China 作者:   收藏  |  浏览/下载：40/0  |  提交时间：2013/03/25 Considering laser medium thermal lens effect and thermal focal length changes with pumping power  conventionally  lasers are designed to operate in the middle of thermal stable zones  where the fundamental mode size is insensitive to thermal perturbation  while this method seems impossible when large fundamental mode size is required. Through self-select mode cavity  lasers are designed to work at the border of stable zone instead  where large fundamental mode size in gain media can be reached. With increase of pumping power and self-aperture mode-selective effect  mode size would grow up automatically to a certain value suitable for monomode resonance. With double 180 W pump modules  acoustic Q-switch and LBO external frequency-doubled  over 28 W which M2 equals 4.5 quasi-CW output green laser and 52W 1.064 um IR output is obtained simultaneity. With the insertion or not of the harmonic separator by footswitch  high beam quality green  IR  and green IR lasers are obtained conveniently.   Approximate analytical description for fundamental-mode fields of graded-index fibers: Beyond the Gaussian approximation 期刊论文  OAI收割 j. lightwave technol., 2001, 卷号: 19, 期号: 1, 页码: 54, 59 Cao Q; Chi S 收藏  |  浏览/下载：1344/227  |  提交时间：2009/09/18 fundamental mode  optical waveguide  power-series expansion  single-mode fiber
