For maximum polarization, the incoming light must have an incident Angleof 30 degree, and the camera is aimed at the subject at an Angle of 30 degree from the other side (see image below).
This refractometer is polarization dependent, and the polarization dependency raise with the increase of grating tilted angle.
同时这种折射计具有偏振依赖性，随着光栅倾斜角的增大偏振依赖性提高。

The results show that the factors are the refractive index thick ness layer number of one-dimensional dual photonic crystal polarization and incident Angleof incident ray.
