Abstract
The light-guide module for emitting particular polarized light beams includes a splitter for separating non-polarized light beams, a transformer for converting polarization of light beams, and a non-polarized light source. The non-polarized light source emits light beams. Particular polarized light beams pass the splitter and other light beams are reflected by the splitter. Polarizations of reflected light beams and of light beams emitted by the non-polarized light source are converted by the transformer so as to separate the light beams later. Thus the light-guide module for emitting particular polarized light beams loses relatively little light energy.
