HOLOGRAM SYSTEM AND METHOD

A hologram system 10 is comprised of two identical volume holograms 14,18. Both holograms have Bragg planes oriented perpendicular to the surface of the hologram. The first volume hologram 14 separates a single beam 32 into two orthogonal polarization component beams 34,36. The second volume hologra...

description A hologram system 10 is comprised of two identical volume holograms 14,18. Both holograms have Bragg planes oriented perpendicular to the surface of the hologram. The first volume hologram 14 separates a single beam 32 into two orthogonal polarization component beams 34,36. The second volume hologram 18 diffracts one of the polarization component beams 34 such that a desired separation angle SA is achieved between the two beams 34,36. This separation angle SA may be precisely adjusted during manufacture by orienting the Bragg planes of the second volume hologram 18 at a rotational angle with respect to the Bragg planes of the first volume hologram 14.
