1. A method for printing a hologram, comprising:
- transmitting a laser light beam;
splitting the laser light beam into an object beam and a reference beam;
adding phase information to the object beam using a spatial phase modulator to form a phase controlled object beam;
directing the reference beam and the phase controlled object beam to a predetermined location on a holographic media to enable the reference beam and phase controlled object beam to form an interference pattern on the holographic media.

Abstract
A system and method for printing a hologram are disclosed. The method includes the operation of transmitting a laser light beam. The laser light beam can be split into an object beam and a reference beam. Phase information can be added to the object beam using a spatial phase modulator to form a phase controlled object beam. The reference beam and the phase controlled object beam can be directed to a predetermined location on a holographic media to enable the reference beam and the phase controlled object beam to form an interference pattern on the holographic media.
