POLARIZED PROJECTION ILLUMINATOR

摘要

The present disclosure relates generally to an optical element, a light projector that includes the optical element, and an image projector that includes the optical element. In particular, the optical element provides an improved uniformity of light by homogenizing the light with lenslet arrays, such as fly-eye arrays (FEA). The FEA is positioned to homogenize a polarized combined light after an unpolarized input light is converted to a single polarization state.
