J. Krasa et al., DEPOLARIZATION OF LIGHT BY AN IMPERFECT POLARIZER, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 48(4), 1993, pp. 3184-3186
The intensity of originally unpolarized light passing through three li
near polarizers from which the first two were identical and crossed wa
s shown to be fully independent of the azimuthal angle of the third (t
esting) polarizer. This means that the second polarizer acts as a depo
larizer of light polarized by the first one. We interpret the phenomen
on phenomenologically on the basis of Mueller calculus in which polari
zed light is described by Stokes vectors.
