摘要
介绍了一种受到视宁限制的光机系统的光学抖动,针对系统波前误差的中高频分量,引入功率谱方法,提出一种波前光学抖动的评价方法并将此方法应用于激光平面波前的实际检测结果,得出了该系统光学抖动的频域特性.该方法可对受视宁限制的光机系统的误差测量与分析有很好的帮助;同时,对光学系统波前质量的评价有一定的指导意义.
Abstract
The essential principle of optical wavefront jitter for seeing- limited in large aperture telescope is presented.The mid and high frequency deviations from perfect wavefront are processed by power spectral density,which is used to evaluate the optic jitter.And it is applied to the plan wavefront measurement for laser,representing the jitter properties in frequency domain.This method contributes to the error analysis and budget of seeing limited optomechanical system and is useful as guidance for the evaluation of the wavefront quality.
