ABSTRACT:
A hologram, produced by illuminating an object via a coherent light source and associated optics, or by digital components or photographic components, is imaged onto, for example, a television camera to selectively provide either a real time, or a non-real time, system. When written directly onto the camera, the hologram is used in a real time system, whereas the digital or film input to the camera provides the combination for a non-real time system. The image is converted into a corresponding electrical video signal via the camera, and the signal is supplied to a selected spatial light modulator. Subsequent illumination by a read coherent light source reconstructs the hologram into a three-dimensional image of the original subject matter, which then may be viewed via a selected optics system.
