  • Patent number: 11099403
    Abstract: A compact mirror-based three-dimensional (3D) display system with a polarizer between the viewer in a viewing space and a beam splitter. The beam splitter may be a half-silvered mirror, and the polarizer may be a circular polarizer that acts to cancel the undesired reflections including that of a viewer. A half prop often will be positioned between the beam splitter and the polarizer. The mirror-based 3D display system may also utilize additional components for creating effects that move in depth and that are in 3D. This may include rotation of the display (or its monitor or display screen) from parallel to an offset angle to allow displayed images to move toward and away from the mirror and not be locked into a plane parallel to and often abutting the mirror. The display system may further include configurations that provide a backdrop image behind the displayed image.
