Patent ID: 7196849

Claim:
A head mounted display for forming images in a user's eye, said display comprising: a spatial light modulator comprising an array of pixels that can be selectively modulated to create a pattern; a light source comprising a plurality of emitters, each of said emitters outputting a different color light, one or more light pipes disposed with respect to said light source to receive light from said plurality of emitters, said one or more light pipes configured to split the light output by each of said light emitters into first and second portions having substantially identical wavelength characteristics, said one or more light pipes having outputs for outputting said first and second portions; first and second polarizing reflective surfaces disposed to receive said first and second portions of light, respectively, said first and second reflective surfaces inclined or declined with respect to each other to reflect said first and second portions of light to first and second sections of said spatial light modulator; at least one polarizer disposed such that said first and second portions of light received by said first and second polarizing reflective surfaces are polarized; first and second diffusers disposed in respective first and second optical paths between said outputs of said one or more light pipes and said first and second polarizing reflecting surfaces; imaging optics disposed with respect to said spatial light modulator to receive light from said first and second sections of said spatial light modulator for imaging said pattern formed by said spatial light modulator; and a head gear for supporting at least said spatial light modulator and imaging optics.
