Manipulation 2D polarization
After I've finished colimate my beam in the camera, I changed the orientation of my HWP and QWP to get 90° for the azymuthal angle and 0° for my elipticity.

Then, I made measurement with only 1 LCD of the polarization when we put a video on the LCD (video = all the 256 RGB value).
I did the same with 1 LCD oriented at 90°.

After doing this, I put the two different LCD and adapt my setup in order to get two different video, which allows you to combine the 256*256 different combinations.

All the setups seems to work.

Note : The camera is not synchronized with the 2 video make with a python.
