NettetThe coordinate (S1, S2, S3) defines any polarization state on or inside the Poincaré sphere. We also need to define a fourth value, S0, to be the intensity of the beam, and we set the diameter of the sphere to be S0. These four values make up the Stokes vector: S = ( S 0, S1, S2, S3) NettetWhen unpolarized light passes through a polarizer, its intensity is reduced by 50%. Analyzer: When polarized light passes through a polarizer, its intensity will be reduced by a factor dependent on the orientation of the polarizer. This property allows us to deduce the polarization of light by using a polarizer.
