Abstract
An optical device capable of homogenizing luminous energy and homogenizing polarized light simultaneously, and an optical illumination system of a projector having decreased volume by using the optical device for homogenizing luminous energy and polarized light has small volume, but is able to homogenize luminous energy and transform non-polarized light a polarized light simultaneously. It is possible to attain homogeneous luminous energy and light efficiency improvement on a level, which are equal to those attained by using conventional Fly eye lens and PBS array, by using the above-described optical device for homogenizing luminous energy and polarized and the volume of the optical system can be decreased and be lightweight.
