With two autocollimations and a big flat mirror, the precision of the parallelization tester can be better evaluated 利用两个精度为0.1"的自准直平行光管和一块平面反射镜检测平行度测试仪精度。
The relation between form errors of the flat mirror under test and wave-front aberrations, i . e ., influence function, can be obtained through sampling the pupil plane 摘要通过在光瞳面上取点的方法,找出被检平面镜面形误差与检验系统波像差之间的相互关系,即影响函数。
A linear equation set can be solved by means of least square method, thus the form errors of the flat mirror under test can be obtained and the form of the flat mirror can be fitted 利用最小二乘法求解一组过定线性方程组,求得被检平面镜的面形误差,拟合出被检平面面形。
