Patent number: 5293259Abstract: A holographic display and method for displaying hologram are disclosed. The method and apparatus provides a compact display arrangement in which the light source for illuminating the display is integral with the display, or in other words, an external light source is not necessary.

The display includes a pair of spaced transparent glass sheets, with the light source disposed between the glass sheets. The holographic plate formed with the converging reference beam is then mounted upon one of the glass sheets, with the light source illuminating the holographic plate with diverging illumination light. A mirror is associated with each of the transparent glass sheets at a location adjacent to the light source, with the reflective surfaces of the mirrors facing each other.Type: GrantFiled: December 7, 1992Date of Patent: March 8, 1994Assignee: The University of Alabama in HunstvilleInventors: Qiang Huang, John A.
