i don't see exactly how can your polarizer filter metallic reflected light? is there a layer on top of the mirror? is the light source shone on the mirror initially polarized (eg. from LCD monitor?)?

Can you please explain me as I'm still wondering what's happening . . . I'm unable to Understand . . .

@asian7779

A CPL consist of two layers, (1) linear polarizer and (2) 1/4 phase plate. The linear polarizer keeps the light in one polarization and he phase plate changes linearly polarized light to circular polarized.

If you pass linearly polarized light thru (1) first, either all of the light will be absorbed or transmitted, depending on the rotation.

If youi pass linearly polarized light thru (2), (2) will make the light circularly polarized so some of it will always pass through (1).

That's interesting. When I first watched it I had no idea what was going on.
