Abstract
Methods, systems, and apparatus, for optical depolarization. One optical depolarizer includes a light-combining module comprising a birefringent prism, wherein an optic axis of a first crystal of the birefringent prism forms a 90° angle with an optic axis of a second crystal of the birefringent prism; and a depolarization module, wherein the depolarization module is disposed at a light emitting end of the light-combining module, the depolarization module comprising a light splitting component and a light-combining component disposed at an emitting end of the light-splitting component, and a delayer disposed between the light-splitting component and the light-combining component, wherein the delayer is disposed on an emitting optical path of the light-splitting component.
