When the lighting is not polarized over the plate a second plate placed parallel to La thyroid. While rotating the plates, one plate, a la the brightness of thyroid exposure through a second sheet of thyroid changes of la to the brightness of the light to the most. When the direction of polarization of the two is parallel to La thyroid and minimum brightness when the direction of polarization of the two perpendicular la thyroid (if the thyroid is very good quality ass, there will be no light comes out!), light reflected from the surface of an object is affected by the angle of fall right into the light polarization phrao.The direction of the electric polarization of light with direction changes reverted back in. When the rotating plate in the direction of the strokes leave thyroid polarization is parallel to the direction of. Change back to the source of the electric light was passed out, but if it gives light to the two perpendicular directions. The light will be Dim for light suck cause polarization does not pass the plate a la thyroid which revolves around. The light does not change the polarization of light waves. Can make the process of polarization by reflection. (Reflection) 2. refraction complex (Double Refraction) 3 filter specification Sheng (Scattering.
