A DLP optical structure and corresponding method of controlling it are described including an optical integrator system having an optical integrator, a relay lens system, a TIR prism assembly, a digital imager, and a projection lens, said optical structure being adapted to accept a polarized light beam, said DLP optical structure comprising: at least one retarder positioned after said optical integrator for controlling the polarization state throughout said DLP optical structure, and achieving the desired polarization state after said projection lens; wherein said desired polarization state is substantially linear or circular. A DLP optical structure is also described including an optical integrator, a relay lens system, a TIR prism assembly, a digital imager and a projection lens, wherein the integrator is a fly-eye integrator for maintaining an input polarization of a light beam, and wherein said input polarization is linear or circular. DLP optical structures for use with a digital imager and a projection lens are also described, substantially as above but not including the features of the digital imager and projection lens. |
