Take grating diffraction and polarization optics as theoretical foundation  second  furthermore  combined with electronics knowledge to analyze the system. First  make use of autocollimation diffraction of grating  measurement information obtained by dual-frequency laser belongs to ac signal  the interferometer measurement system take grating pitch as measuring datum  the structure is simple  possess great gain and high signal-noise ratio  therefore  stable  completely overcome the disadvantages of DC level drift caused by light intensity variation of single-frequency laser  system can achieve nanometer resolution. 2010 IEEE.  reduce the impact of environmental factors  easy to install and debug  measurement error is small   Developing of in-suit long trance profiler for testing slope error of aspherical optical Elements (EI CONFERENCE) 会议论文  OAI收割 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China Zhou C.; Li H.; Chen C.; Zhou C.; Qian S. 收藏  |  浏览/下载：43/0  |  提交时间：2013/03/25 Profile error of super smooth surface of optical elements at X-ray/EUV in synchrotron radiation (SR) light beam line is described as slope error of them generally. The Long Trace Profiler (LPT) is used for testing surface slope error of SR optical elements in world generally. It is requisite to use In-suit LTP measuring surface thermal distortion of SR optical elements with high heat under high bright SR source. Authors design an In-suit LTP by means of co-path interferometer with pencil light beam. The instrument not only can be used for testing slope error of mirrors in Lab. also in situation test the distortion of mirror with high heat load at synchrotron light beam line. The device can be used to test various absolute surface figures of optical elements such as aspherieal  spherical and plane. It is needless standard reference surface. It is named by LTP-III. This paper describes its basic operating principle  optical system  mechanical constructions  DC serve motor control system  array detector  data acquisition system and computer system for controlling and data analysis of LTP-III. The Instrument has advantages of high accuracy  low cost  multifunction and wide application. Length of surface measured of optical element accuracy is 0.04 arcsec.
