Abstract:
An image projector comprising:light source means for generating illuminating light;a light valve for spatially modulating the illuminating light and for forming an optical image for projection;a projection optical system for projecting optical images onto a screen, said projection optical system having an aperture;a reflecting member, located at said aperture of said projection optical system, for reflecting the illuminating light from the light source means; andan optical integrator, located between the light source means and the reflecting member, for splitting the illuminating light from the light source means and for forming multiple secondary light source images at the aperture of the projection optical system,wherein the illuminating light from the light source means is reflected by said reflecting member such that the illuminating light strikes the light valve after passing through a first half of an effective light pass through area of the aperture, and said optical image for projection is passed through a second half of the effective light pass through area of the aperture.
