| 20100238270 | ENDOSCOPIC APPARATUS AND METHOD FOR PRODUCING VIA A HOLOGRAPHIC OPTICAL ELEMENT AN AUTOSTEREOSCOPIC 3-D IMAGE - Apparati and methods for generating a three-dimensionally perceived image from a stereo endoscope by at least one viewer include an autostereoscopic display having a left projector and a right projector that project corresponding left and right images received from corresponding left and right cameras of a stereo endoscope through a transmissive holographic optical element functioning as a Bragg diffraction grating to redirect light from the left projector to a left eye-box and to redirect light from the right projector to a right eye-box for viewing by left and right eyes of a viewer to create a three-dimensionally perceived image without glasses or optical headgear. | 09-23-2010 |
