Abstract

We describe a method to create and reconstruct computer-generated Fourier-transform holograms in photorefractive materials. Holographic reconstructions are obtained from computer-generated data by imaging computer-generated holograms into a BaTiO3 crystal, using either spatially coherent or incoherent light. The intensity variations in the images produce a phase hologram in the crystal by the photorefractive effect. The diffraction efficiency of the holographic reconstructions depends on imaging system f number, crystal orientation, and read-beam polarization. Because these holograms are recorded by using (incoherent or coherent) images rather than coherent interference patterns, our system provides a new technique for the holographic display of computer-generated information.
