Projecting Stereoscopic Image in a Compact Immersive Spherical Display "SpinDome"

Abstract

The "SpinDome" is an image display using wide-angle spherical screen. Sphere is an ideal shape of a screen that covers human visual field. The optical system of the SpinDome employs two mirrors: a flat mirror and a spherical convex mirror. The flat mirror bends the light so that the viewer can see the image from the center of the spherical screen. This optical configuration enables seamless wide-angle image in a very limited space. A rotary mechanical shutter is set in front of the projectors, which provides stereoscopic image. Effectiveness of the display is exemplified by maneuvering a remote vehicle.
