First  establish an appropriate extrapolation model based on the existing data series  and then fit correlation functions other than existing data by derivative least squares method  finally perform spectrum analysis using extrapolated correlation functions. Numerical simulations and the experimental results show that good results are achieved no matter correlation functions change slow or rapid  and the extrapolation error is not more than 2.3%. 2012 Springer-Verlag Berlin Heidelberg.   Imaging system effects on the measuring accuracy of the optical surface in interferometer (EI CONFERENCE) 会议论文  OAI收割 3rd International Conference on Measuring Technology and Mechatronics Automation, ICMTMA 2011, January 6, 2011 - January 7, 2011, Shanghai, China Yang W.; Liu M.; Xu W. 收藏  |  浏览/下载：61/0  |  提交时间：2013/03/25 In order to measure high accuracy or mid spatial frequency optical surfaces  this study investigated imaging system in Fizeau interferometer. Interferometer is a transferring phase information system. General transfer function can't evaluate the ability of imaging system in interferometer that transfers the phase information of the optical surface. So this paper deduced instrument transfer function (ITF) and used ITF to evaluate the phase information transfer ability of interferometer. We obtained some results about ITF of imaging system by numerical simulation when there are different aberrations in imaging system or measuring optical surfaces were different. Our results indicate that ITF can evaluate the ability of transferring phase information in interferometer and the distortion of imaging system evidently affects the accuracy of interferometric measurements. 2010 IEEE.   A new method of surface modeling and its application to DEM construction SCI/SSCI论文  OAI收割 2007 Yue T.
