Patent ID: 8425042

Claim:
A projection system comprising: an imager for sequentially emitting left-eye and right-eye images; an optical retarder having a plurality of segments including a first segment and a second segment, the first segment for converting left-eye images to a first polarization, the second segment for converting right-eye images to a second other polarization; and an actuator for one of rotating and translating the optical retarder according to timing synchronization of the left-eye and right-eye image emissions such that a polarized beam of light incident on the first segment samples a first fast axis orientation that is substantially constant relative to itself over time as the optical retarder is one of rotated and translated, and such that the polarized beam of light incident on the second segment samples a second other fast axis orientation that is substantially constant relative to itself over time as the optical retarder is one of rotated and translated.
