由光线造迹和三级像差理论计算大抛物面的Ronchi弯线条。
2) wobbly line
弯弯曲曲的线条
3) That line got out of straight.

5) Ronchi grating
Ronchi光栅
1.
The accurate measurement of angle based on Talbot effect of Ronchi grating;
基于Ronchi光栅Talbot效应的角度精确测量
2.
The measurement is realized by calculating the angle of moiré fringe formed by Talbot image of one Ronchi grating and another Ronchi grating.
这种方法是通过对一块Ronchi光栅的Tal bot像与另外一个Ronchi光栅所产生的莫尔条纹转角的计量来测量长焦距;通过扫描对大口径范围内的整个区域进行测量。
3.
When a plane wave passes through a lens and illuminates on a Ronchi grating, Talbot images will appear at periodic Talbot distance behind the grating, the period of the Talbot image of the Ronchi grating has a relationship with the long foca.
这种方法的原理:平行光束经过被测透镜后照射在Ronchi光栅上,在Rochi光栅后周期性的位置会形成Talbot像,在光栅Talbot像的位置再放置一个相同的Ronchi光栅就会产生莫尔条纹,当入射的平行光束在垂直于光栅栅线方向有个微小的角度变化,莫尔条纹就会产生一个相应的明显移动;由莫尔条纹的原理可知,莫尔条纹的移动量与入射平行光束的变化角度有一个对应关系。
6) Ronchi test
Ronchi检验法
1.
Profile measurement for micro-varying liquid surface based on chessboard grating Ronchi test;
基于棋盘光栅Ronchi检验法的微变液面测量
