Patent ID: 7360899

Claim:
An apparatus comprising: a prism comprising: a substantially optically transmissive body having first and second input ports for receiving light, an output port for egress of light, and a front face opposite said output port; a first reflecting polarization beamsplitting surface comprising a wire grid polarizer angled with respect to said first input port to direct polarized light received by said first input port through said output port; and a second reflecting polarization beamsplitting surface comprising a wire grid polarizer angled with respect to said second input port to direct polarized light received by said second input port through said output port; and a reflective spatial light modulator, wherein said prism is disposed with respect to said reflective spatial light modulator such that said polarized light received by said first and second input ports is delivered to said reflective spatial light modulator via said output port and is reflected from said reflective spatial light modulator through said front face of said prism.
