8.3: A Minimum Dispersion Stereoscopic Rear Projection Display

One design method of the 3‐D stereoscopic display system is based on polarization separation of the binocular parallax images [1] [2]. Usually two orthogonal linearly polarized lights are used in such a system, however it suffers from cross‐talk between the binocular parallax images in case of tilting the viewer's polarization glasses. In this paper, we introduce a stereoscopic rear projection display system based on circularly polarized lights to circumvent the drawback of the conventional system. Furthermore, we use a broadband retarder, which is designed by a direct binary search (DBS) algorithm, to provide chromatically non‐dispersive stereoscopic images. This method can be designed for high performance stereoscopic requirements such as in those systems for medical application.
