ABSTRACT:
A first volume hologram diffracts a portion of the beam of light as a first beam and transmits the remaining portion of the beam of light as a second beam. A second volume hologram diffracts either the first or the second beam to a desired angle and transmits the remaining beam undiffracted. Desired beam separations at desired angles may thereby be achieved for use in optical data storage systems.
