Abstract
A hologram recording system useful for recording holograms for use on a film strip tape in an optical retreival system is disclosed. The recording system permits accurate centering of a selected one of a series of frames. A hologram for use on a film strip tape is recorded with interfering divergent beams of .lambda..sub.1 wavelength coherent wave energy for readout with a plane wave of .lambda..sub.2 wavelength coherent wave energy to provide a reconstruction in a plane spaced a preselected distance Z.sub.3 from the plane of the hologram record being read out. The respective distances Z.sub.1 and Z.sub.2 of the effective optical crossovers of the two divergent recording beams from the plane of the hologram recording medium are uniquely functionally related to the preselected distance Z.sub.3 and the ratio .lambda..sub.2 /.lambda..sub.1.
