Abstract

A beam-shaping optical element, an illumination optical system that contains the beam-shaping optical element, and a laser projection display system that contains the illumination optical system is provided. The beam-shaping optical element is composed of a Diffraction Optical Element (DOE) lens array and a focusing lens. These components change the RGB laser beams to those having a rectangular shape and an intensity distribution made uniform regardless of the directions or locations of the entering light beams. The beam-shaping optical element makes high efficiency, ultra-compact size, and low cost of a laser projection display system possible.
