Abstract
Depolarizing system for polarized light formed of a birefringence crystal wedge which receives the beam of polarized light at a first surface and outputs spatially depolarized light from its output surface. The wedge may include small steps on one of the surfaces or special orientations to depolarize the light. The wedge may be substantially triangular in shape so that the surface decreases from one side to the other.
