Abstract

In this paper, new configuration of inner optic module of LCD projectors for polarized stereoscopic projection with no light loss in the process of polarization is proposed. In the proposed system, two polarizing filters or waveplates, which have been employed in the conventional LCD polarized stereoscopic projection systems and consequently caused an additional light loss and image distortion, are excluded by modifying the inner optic module of LCD projectors and some steps of image processing, so that maximum light efficiency in the polarization process can be obtained from the proposed method.
