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.   Wave-front Sensing and correction for 4-meter LAMOST 会议论文  OAI收割 San Diego, CA, 2008-8-2 作者:  Jiangpei Dou;  Yongtian Zhu;  Xi Zhang;  Deqing Ren 收藏  |  浏览/下载：24/0  |  提交时间：2014/01/02 wave-front sensing  residual aberration  LAMOST  LabVIEW
