The angular displacement of reflecting surface is measured in accordance with the direction change of Moire fringes caused by the inclination of grating. self-imagingplane.
利用光栅自成象面的倾斜引起莫尔条纹方向变化来测量反射表面的角位移。

When using the IR sensor, the size of the target in the imagingplane of the camera is only one pixel or several pixels and the signal received is very weak when the target is far away in distance.
