IMPROVED OVER-UNDER LENS FOR THREE-DIMENSIONAL PROJECTION

摘要

An over/under lens (300', 300'') for projecting a 3D film print (102) possesses a circular polarization module (450,550) that includes a clockwise circular polarization filter assembly (460, 560) and a counterclockwise circular polarization filter assembly (461, 561). The clockwise and counterclockwise circular polarization filter assemblies advantageously limit cross talk occurring between left-eye and right eye images, thus improving the viewing experience.
