摘要
从光学平行差入手,导出了有角度制造误差的五角棱镜的像方坐标系和作用矩阵,分析了角度制造误差引起的扫描激光束转向的波前误差,提出了调整五角棱镜的依据,有利于减小角度制造误差对大口径透镜望远镜波前测量的影响。
The optical parallelism errors are analyzed, the image reference frame and the action matrix of a pentagonal prism with processed angle errors are educed. Then light-turning frontwave errors of scanning laser caused by processed angle errors are analyzed and how to adjust a pentagonal prism is proposed. This is useful to diminish processed angle error effect on the frontwave measurement of a large aperture lens telescope.
