Abstract:
An image projection system comprising:a reflector for reflecting rays of light from a point source located at the focal point of said reflector;a matrix array of microscopic lenses arranged on a first plane and a matrix array of microscopic lenses arranged on a second plane, each lens of the first plane focusing light from said reflector onto a corresponding one of the lenses of the second plane;a plurality of optical elements arranged on a third plane for splitting light from said second plane into a first polarized component and a second polarized component parallel to the first, and converting the second polarized component to a polarization identical to the first polarized component;a focusing lens system for focusing light from the third plane onto a fourth plane;a display panel on said fourth plane for imagewise-modulating light focused thereon by said lens system; anda projecting lens system for projecting the imagewise-modulated light onto a screen,said reflector being configured so that any point on said reflector is defined by an equation containing a term of parabola and at least one term of a series of aspheric coefficients of order of even number which is equal to or greater than two.
