Abstract
A three dimensional display system is shown wherein a scanned light beam is displayed upon a continuously rotating display member rotating about a fixed axis. A first embodiment provides that the display member be comprised of a pair of intersecting display surfaces. In a further version the display member is fixedly positioned in a spherical enclosure which is rotatable in two different directions. In a second embodiment, the display member is formed by a bundle of fiber optic elements extending from an image projector to a viewing surface. The optical fiber bundle can be formed so that the image receiving portion has a smaller cross section than the image transmitting portion. In a third embodiment, the angle formed between the display member and the axis about which it rotates is adjusted, on or off line, by changing the length of an adjustable rod secured to the display member and a member rotating with the display member. In a fourth embodiment, a three dimensional display and two dimensional display are combined in conjunction with an optical combiner. In a fifth embodiment, the light is transmitted to the rotating disc through a pair of changeable rotating apertured disks wherein the apertures are aligned. In a further embodiment of the invention, the screen is formed from a pair of symmetrical stepped disks in the shape of a helically shaped half circle.
