A stereoscopic projector with polarized glasses is proposed that consists of spatial light modulators (SLM’s) that control the retardation of projected light, a polarization beam splitter (PBS), and single-projection optics. This display’s features include a three-dimensional (3-D) image display with a single projector and half the size and the power consumption of a conventional 3-D projector. Analysis shows that the cross talk and the extinction ratio of this system depend strongly on the polarized light-separation characteristics of the PBS, the light output, and the extinction ratio of the SLM’s. A double-PBS method that drastically improves 3-D image quality is also discussed.
