摘要
提出一种新的二维波前延拓剪切干涉的实验装置 ,利用光栅滤波实现波前延拓剪切干涉 ,大大简化了光学装置 。
Based on optical information processing,the Wavefront Prolongation Shear Interference(WPSI) by spatial filter of grating is firstly prompted. Compared with conventional WPSI setup with joint of several interferometers, it is quite convenient and exercisable.
