We report the experimental demonstration of a photorefractive dynamic holographic memory that has a simple feedback architecture stabilized through a novel spatial sampling technique. By using dynamic copying to compensate for photorefractive decay, this memory provides nondestructive readout, selective erasure and rewriting, and real-time adaptation of holograms through an arbitrarily large nu...

Hidden surfaces eliminated Sorting To enable visibility prefiltering, the visible parts of the projected scene primitives have to be determined exactly. We employ parallel hidden surface elimination for this task. The computations can be executed in parallel for all edges of the input triangles. This provides sufficient data parallelism to effectively use massively parallel hardware such as GPU...

A sampled phase-only hologram (SPOH) is the phase component of an object image with pixels being a periodic grid-cross pattern. The reconstructed SPOH sparse abundant empty voids and degradation in sharpness contrast. In this paper we proposed method based on new sampling scheme, together stochastic binary search (SBS), to obtain optimal lattice that can be applied generate holograms enhanced i...
