Abstract

Previous techniques for multiplexing volume holograms include angle, wavelength, phasecode, and peristrophic multiplexing. We have developed a new technique, which we call shift multiplexing, in which the medium is shifted relative to a reference beam composed of either a single spherical wave or multiple plane waves. This technique is particularly well suited to disk applications, in which the motion of the disk relative to the reading head can be used to perform multiplexing.
