Abstract
A stereoscopic display system and method of stereoscopic projection that include a polarization-switching light source and a polarization-preserving projector. The polarization state of the polarization-switching light source is synchronized with alternate projection of left-eye images and right-eye images. The polarization-switching light source may include a laser and a rotating disk, and the disk may include a waveplate that switches the polarization state as the disk rotates.
Claims21
A stereoscopic display system comprising:
- a polarization-switching light source characterized by a polarization state;
- and
- a polarization-preserving projector which is illuminated by the polarization-switching light source.
A stereoscopic display system comprising:
- a polarization-switching light source characterized by an original polarization state;
- a projector which is illuminated by the polarization-switching light source;
- and
- a polarization compensation element;
- wherein the polarization compensation element compensates for a polarization change in the projector.

A method of stereoscopic projection comprising:
- generating a light which is polarization switched;
- modulating the light to make a left-eye digital image and a right-eye digital image;
- and
- projecting the left-eye digital image and the right-eye digital image alternately to form a projected left-eye digital image and a projected right-eye digital image.
