Abstract:
An image projector comprising:a light source having an elliptical reflector; a color filter that transmits a predetermined beam of light of a predetermined wavelength from beams of light focused from the light source; a reflective plate that reflects the predetermined beam of light transmitted through a color filter; a rod lens that converges the predetermined beam of light from the reflective plate to make a distribution of the predetermined beam of light uniform; a first illumination lens part that diverges the predetermined beam of light of a uniform distribution from the rod lens, and focuses the predetermined beam of light onto a plurality of focusing points; a polarization beam sprite array that polarizes the predetermined beam of light from the first illumination lens in a predetermined direction; a second illumination lens part that focuses the polarized beam of light from the polarization beam sprite array; a polarization prism having a polarization split plane for transmitting or reflecting the focused beam of light; a reflection type display for producing a picture beam according to a video signal by using a reflected beam of light; and a projections lens for enlarging and projecting the picture beam.
