ABSTRACT:
A portable holographic display system emboding holographic plates which are disposed upon a plurality of thin film holographic emulsions coupled to multiple channel Kerr units that generate a series of multi-colored holographic images. The holographic images generated by transmission thin film emulsions are based on the number and order that multiple light channels, fiber optics elements and thin film holographic emulsions are illuminated. The process of illumination depends directly on the activation sequence of lens elements or cells, which contain an optically active medium controlled by command signals from a central control means coupled to a source of electrical power.
