Hologram synthesis for photorealistic reconstruction [PDF]
Journal of the Optical Society of America A, 2008 Computation of diffraction patterns, and thus holograms, of scenes with photorealistic properties is a highly complicated and demanding process. An algorithm, based primarily on computer graphics methods, for computing full-parallax diffraction patterns of complicated surfaces with realistic texture and reflectivity properties is proposed and tested ...
