摘要： The present invention relates to improvements in a three-dimensional display system. A transformation technique is described wherein deflection coordinates defining the spatial locations of the images written into the display volume are determined by transformation from a coordinate system based on the display volume to a coordinate system based on the one or more electron guns. The application further relates to a technique by which the location of an electron beam within the display volume may be determined. These techniques involve positioning conductive material at various locations such as the screen and the enclosure of the display itself so that the impinging electron beam may be detected and thy the location of the beam in the display volume may be derived. Image enhancing techniques are described in conjunction with the location techniques whereby conductive films are evaporated onto the screen and/or the enclosure. Modifications in voxel plotting techniques are described so as to enhance the quality of the image produced in the display volume. The technique includes interlacing the scanned print location. An additional improvement is provided by a particular conduction medium configuration superimposed or deposited onto the screen where the conducting medium incorporates information which is extracted or read from the medium by scanning a particle beam across its face so as to invoke momentary voltages or currents in the conducting medium.

摘要： A three-dimensional display device comprising an evacuated enclosure (45). A phosphor coated screen (44), means to rotate the phosphor coated screen, one or more electron gun (41-43) and control means to drive the one or more electron gun. Sequential image Frames (FIGS. 2b-2f) are written to the rotating phosphor coated screen (44) by the one or more electron gun (41-43) for a number of image sectors. Provided the screen rotates sufficiently rapidly and the phosphor coating has the required persistence the human eye will perceive a three-dimensional image within the display volume swept out by the phosphor coated screen. In the preferred embodiment the planar screen (44) rotates about a vertical axis with three electron guns (41-43) located below the display volume directed upwardly towards the center of the display volume. In another embodiment the display screen is in the form of a helix (51) with the electron gun (52) being aligned substantially along the axis of rotation of the helix.
