Patent ID: 7445339

Claim:
An arrangement for enabling an image to be viewed, comprising: a screen having a polarization selective property with different angular diffractions; and a projector for projecting the image on the screen for viewing by a viewer, the projector including an assembly for emitting laser beams of different, mutually orthogonal polarizations, and a scanner for sweeping one of the laser beams of one of the polarizations along scan lines comprised of pixels, selected ones of the pixels on the scan lines being illuminated by the one laser beam to form a first subimage on the screen, the scanner being also operative for sweeping the other of the laser beams of the other of the polarizations along additional scan lines comprised of pixels, selected ones of the pixels on the additional scan lines being illuminated by the other laser beam to form a second subimage on the screen, both subimages being viewable by the viewer from different viewing angles as a three-dimensional image due to the different angular diffractions for the mutually orthogonal polarizations.
