Abstract

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). A first FEA is positioned to intercept and converge an unpolarized combined light before the light is converted to a single polarization state, and a second FEA is positioned to intercept and diverge the converted light having a single polarization state.
