    Abstract: An optical illumination system comprising a waveguide (16) that accepts light generated by a light source (14) and transmits the light via total internal reflection. Attached on one surface of the waveguide is an array of microprisms (28) and a polarizing film (44) disposed between the waveguide (16) and microprisms (28). The polarizing film (44) transmits light polarized in a first polarization state and reflects light polarized in a second polarization state. The reflected light is converted to light of the first polarization state to allow the light to transmit through the polarizing film (44).
