An innovative beamsplitter-based stereoscopic/3D display design

A novel stereoscopic/3D desktop monitor has been developed that combines the output of two active matrix LCDs (AMLCDs) into a stereo image through use of a unique beamsplitter design. This approach, called the StereoMirror, creates a stereo/3D monitor that retains the full resolution, response time and chromaticity of the component displays. The resultant flicker-free image, when viewed with passive polarizing glasses, provides an unprecedented level of viewing comfort in stereo. The monitor also is bright enough to use in normal office lighting. The display has excellent optical isolation of the two stereo channels and a wide viewing angle suitable for multi-viewer use. This paper describes the architecture of the system and the principal of conservation of polarization that results in the full-definition stereo image. Optical performance results are also described. Practical considerations will be discussed, including system interface requirements, conversion between stereo/3D and monoscopic viewing and comparison to other stereo display approaches. The higher level of performance provided by the StereoMirror allows for stereo viewing to be viable in new imaging markets as well as permitting a more effective use of stereo in existing markets. These applications are discussed.
