Paper Abstract

Polarized stereoscopic projection involves the polarization of the two projected images in orthogonal directions -- e.g. +/- 45 degrees for linear polarization, or clockwise and counter- clockwise for circular polarization. When LCD projectors are used for polarized stereoscopic projection it is important to take into consideration the fact that the output of these types of projectors is already polarized -- but not necessarily in the directions required for stereoscopic projection. The paper considers the amount of light loss of various polarized stereoscopic projection configurations to recommend optimal configurations. The paper also points out that it is advantageous that the output of an LCD projector is already polarized. In general, there will be less light loss in the polarization process when an LCD projector is used for stereoscopic projection as compared to when a projector which outputs unpolarized light is used (e.g. CRT and DMD/DLP).
