Abstract

Firstly,Power Spectral Density( PSD) is proposed for mirror surface figure evaluation in the large aperture telescope system as for some difficulties for Root Mean Square( RMS) in the evaluation of large scale variety and disadvantage of robust for rigid body displacement. Then,the decomposition arithmetic of PSD is analyzed with Zernike polynomial,and Zernike polynomial spectrum energy distribution is analyzed in some order. The algorithm has been used in the surface figure evaluation of a Φ 500 mm mirror,and energy distribution in the frequency domain of the actual mirror surface has been obtained. The experimental results indicate that the evaluation of PSD is more practical when used in large aperture mirror for their manufacture and testing and for the error budget allocation in telescope system. Finally,a kind of noncorrelative sub-aperture stitching method for evaluation of reflective mirror shape based on PSD is proposed which can be used in the large aperture telescope.

基于功率谱密度的镜面图形评价
首先,针对均方根法在评价大尺度变化时存在的困难和刚体位移鲁棒性差的缺点,提出用功率谱密度法评价大口径望远镜系统的镜面图形;然后,用Zernike多项式分析了PSD的分解算法,并按一定顺序分析了Zernike多项式谱能量的分布。将该算法应用于Φ 500 mm反射镜的面形评定中,得到了实际反射镜面频域的能量分布。实验结果表明,将PSD评价应用于大口径反射镜的制造和测试,以及望远镜系统的误差预算分配,更为实用。最后,提出了一种基于PSD的非相关子孔径拼接法,可用于大口径望远镜的反射镜形状评价。
