Abstract
An image projection device having a spatial light modulator and a polarized source system for illuminating the spatial light modulator such that light of a first polarization state illuminates one region of the spatial light modulator and light of a second polarization state illuminates another region of the spatial light modulator. Preferably, the image projection device includes a first set of polarization selective light processing elements, including a first conicoid element which passes light of the first polarization state and reflects light of the second polarization state and a second set of polarization selective light processing elements including a second conicoid element which passes light of the second polarization state and reflects light of the first polarization state.

Uniform illumination system

TL;DR: In this article, a planar multi-layered LED light source arrays concentrating their polarized or unpolarized output within a limited angular range are presented. But the optical interaction between light emitters, reflecting sidewalls and the elevated prismatic films create overlapping virtual images between emitting regions that contribute to the greater optical uniformity.
