Patent ID: 8237777

Claim:
A stereoscopic light projection system comprising: a stereoscopic image forming subsystem configured at least to output stereoscopic light comprising modulated left-eye and right-eye light beams, including: a light source subsystem configured to generate left-eye and right-eye light beams, and a light modulation subsystem configured to generate the modulated left-eye and right-eye light beams by modulating the respective left-eye and right-eye light beams in a manner consistent with stereoscopic image data; a light-intensity sensing subsystem including at least one light intensity sensor to sense light intensities in either the left-eye and right-eye light beams or the modulated left-eye and right-eye light beams; and a light-intensity-correction subsystem configured at least to (a) determine a difference in the sensed light intensities between the left-eye and right-eye light beams or between the modulated left-eye and right-eye light beams and (b) control the light source subsystem to change an intensity of the left-eye light beam or the right eye light beam if an absolute value of the determined difference in the sensed light intensities exceeds a threshold amount.
