Abstract : The report describes a holographic optical element that performs a zoom operation in a stepwise fashion while undergoing a simple rotation. Each of four holographic plates is produced by a different optical arrangement. Each plate contains a number of exposures arranged in a ring. The four plates are paired with the exposures in the ring of one plate in proper register with the exposures in the second plate. The resulting pair of holograms form on-axis holographic lenses. The two pair are combined to produce the holographic zoom lens.
