大口径光学元件检测中的主要误差及其影响
Testing errors and its influence of the large aperture optical elements

摘要: 使用PSD作为大口径光学元件的质量评价标准，标定了测试系统的传递函数，并讨论了在对ICF驱动器中所使用的光学元件进行检测时产生的几种主要误差，分析了这些误差在进行计算和分析时可能造成的影响以及消除的方法。Abstract: In this paper, the power spectral density was employed as the specification criterion of the large aperture optical elements. The transfer function of the testing system has been demarcated. Furthermore, the main errors appeared in the testing process and their influences have been discussed in detail. The results show that the low frequency erroe,which caused by the plcement, affect the testing result. And the high frequency error, which caused by the interfeerene, does not have more effect on the testing.
