Exposure compensation for sequential superposition holographic display.
We describe a fast and computationally simple computer-aided holographic technique for producing lowinformation-content 3-D displays by sequential superimposition of point-object Fresnel holograms. An exposure control control algorithm is used to ensure uniformity of exposure across the sequentially superimposed holograms. The result is a significant increase in the number of recordable object points. The algorithm has been used to produce displays containing up to 2800 individual point exposures.
