Abstract

A light pipe based projection engine includes a X-prism (190, 192, 690, 692) transmitting substantially light of a useful polarization in an output direction (112) and reflecting substantially light of a non-useful polarization in a first orthogonal direction substantially orthogonal to the output direction (112), an initial reflector (114, 128) may reflect the non-said low, said medium, and said high bands of wavelengths (106, 108, 110) in a second orthogonal direction substantially orthogonal to the output direction (112) and the first orthogonal direction, and a final reflector (118, 132) may reflect the non-said low, said medium, and said high bands of wavelengths in the output direction (112), the non-said low, said medium, and said high bands of wavelengths may be rotated substantially to light of the useful polarization by the initial (114, 128) and final reflectors (118, 132).
