Using the soft x-ray reflectometer above  the scattering light distribution of silicon and zerodur mirrors which have super-smooth surfaces could be measured at different incidence angle and different wavelength. The measurement when the incidence angle is 2 degree and the wavelength is 1 lnm has been given in this paper. A surface scattering theory of soft x-ray grazing incidence optics based on linear system theory and an inverse scattering mathematical model is introduced. The vector scattering theory of soft x-ray scattering also is stated in detail. The scattering data are analyzed by both the methods above respectively to give information about the surface profiles. On the other hand  both the two samples are measured by WYKO surface profiler  and the surface roughness of the silicon and zerodur mirror is 1.3 nm and 1.5nm respectively. The calculated results are in quantitative agreement with those measured by WYKO surface profiler  which indicates that soft x-ray scattering is a very useful tool for the evaluation of highly polished surfaces. But there still some difference among the results of different theory and WYKO  and the possible reasons of such difference have been discussed in detail. 2009 SPIE.   Dynamic evaluation system for interpolation errors in the encoder of high precision (EI CONFERENCE) 会议论文  OAI收割 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, November 19, 2008 - November 21, 2008, Chengdu, China 作者:  Liang L.-H.;  Sun Y.;  Sun Y.;  Wan Q.-H. 收藏  |  浏览/下载：43/0  |  提交时间：2013/03/25 In order to measure dynamic interpolation errors of photoelectric encoder of high precision  the dynamic evaluation system of interpolation errors is introduced. Firstly  the fine Moire signal of encoder which is collected with the high-speed data gathering card into the computer is treated to equiangular data with the method of linear interpolation. Then  the analysis of harmonic wave with the FFT is processed. Compared with the standard signal  the dynamic interpolation errors of the encoder are calculated. Experimental results show that the precision of the dynamic evaluation system of interpolation errors is 0.1 %( pitch). The evaluation system is simple  fast  high precision  and can be used in the working field of the encoder. 2009 SPIE.
