Measuring Polarizer

I wish to compare the effect of polcam setting on uncertainity (for future measurements), so I generated polarization states with different settings.

Polarization states are measured without BS

1. pol cam with full wave plate rotat 2048 pt fft, scan speed 60Hz

2. pol cam with dual full rotation and 2048 pt fft, scan speed 60Hz

3. full wave plate rotation by 1048pts, scane speed 60Hz (all the previous analysis were done using this setting)

4. Polarizer was installed and measured using generated states

Fig 1 shows the orientation of the polarizer.
