  • Patent number: 4881068
    Abstract: A 3-D visual display apparatus. A sealed chamber having one or more walls transparent to visible light contains a gas having a first excited state and a second excited state which second excited state relaxes with the emission of visible light. A first laser source excites a small first volume of the gas to the first excited state and a second laser source excites a second volume, which is a small portion of the small first volume, to the second excited state which relaxes to emit visible light in all directions from the small second volume. This small light emitting volume appears as a small spot of light. Rapid movement of the two lasers permits the creation of other light emitting spots quickly enough to produce what appears to the human eye as a 3-D display. By proper choice of gases and lasers, visible light in all colors can be emitted from the spots to produce a 3-D color display.
