ABSTRACT:
A moving holographic image is projected into three space by producing a series of slides or fixed holographic images in quick succession in a process similar to a conventional motion picture All of the slides are produced on a single photochromic surface in succession by writing on the surface with UV light. Each slide consists of a set of identical strip holograms positioned on the photochromic surface as an array. Each strip hologram is produced by creating a series of traces arranged side by side. As the maxima traverse the surface, the UV source is turned on and off according to a program to produce a series of dots of either unchanged or darkened color on the photochromic surface. During the next scan a new set of unchanged or darkened dots are produced on each strip hologram, and so on until the slide is completed. After being illuminated the surface is quickly washed clean in preparation for the next slide by illuminating it with a burst of high intensity UV light. The moving holographic image may be produced in full color by producing and illuminating each side in three versions in sequence, one each of the versions being illuminated by coherent light in each of the primary colors.
