A new method is applied in comparing experiment. For real interferometric data of annular wave front  the SEIDEL aberration calculated in different ways is removed from the original wave front. Residual astigmatism aberration in annular polynomial way is close to zero  but defocus and sphere aberration are 0.002709  -0.00182. The residual SEIDEL using annular polynomial is least. Data used in comparison shows that Zernike annular polynomial is more accurate and meaningful for the decomposition of aberrations and the calculation of Seidel aberrations in annular pupil. The calculation in astigmatism aberration is most accurate and those in defocus and sphere aberration are least accurate  when the first 9 terms are used in approximate solving SEIDEL. More coefficients are needed to obtain the real SEIDEL. 2010 IEEE.   Decomposition of ordinary difference polynomials 期刊论文  OAI收割 JOURNAL OF SYMBOLIC COMPUTATION, 2009, 卷号: 44, 期号: 10, 页码: 1394-1409 作者:  Zhang, Mingbo;  Gao, Xiao-Shan   |  收藏  |  浏览/下载：16/0  |  提交时间：2018/07/30 Functional decomposition  Difference polynomial  Difference operator  Difference degree   Characteristic set method for differential-difference polynomial systems 期刊论文  OAI收割 JOURNAL OF SYMBOLIC COMPUTATION, 2009, 卷号: 44, 期号: 9, 页码: 1137-1163 作者:  Gao, X.
