PROJECTION SCREEN FOR A MULTIPLANAR VOLUMETRIC DISPLAY

摘要

The invention features a spinning screen assembly that incorporates a thin projection screen held in place by a hollow transparent mount. The amount may be spherical in overall shape. A projection system projects portions of a 3-D image onto the projection screen. A control electronics subsystem coordinates other subsystems, including the projection system and a source of image data. Persistence of vision causes viewer to perceive a volumetric image from a series of projections. The thinness of the projection screen reduces visual dead zones. Enclosing the projection screen within the screen assembly reduces the air resistance that the thin screen is exposed to during rotation. In a further embodiment, a stationayry hemispherical transparent dome covers the spinning screen assembly.
