grating shearing interferometer

基本解释

This method is realized by using laser grating shearing interferometer and Talbot effect.
这种方法是利用激光光栅剪切干涉仪和塔宝效应实现的。
This interferometer used grating as its shearing part. It has characteristics of simple light route, compact structure, low shockproof.
该仪器利用光栅作为错位元件，具有光路简单，结构紧凑，波像差小，防震要求低等特点。
CCD is used in double-frequency grating shearing interferometer to measure the time and space coherence of light field quantitatively and spherical aberration of gradient-index rod lens.
利用双频光栅剪切干涉法，CCD摄像机采集剪切干涉条纹图，用自行设计的软件对图像进行处理，可定量测量光场的时空相干性以及梯度折射率透镜的像。
