53.1: Real-time Binary Hologram Generation for High-quality Video Projection Applications

Presenting visual information using binary-phase holography has a number of advantages over conventional video projection techniques. However, acceptable image quality for video applications has yet to be realised. In addition, the computational complexity of hologram generation has precluded real-time operation. The authors present a new approach to hologram generation and display which allows high-quality images to be projected holographically, in real time.

Production of computer-generated holograms on recordable compact disk media using a compact disk writer

It is often necessary in optical experiments to produce computer-generated holograms (CGHs) of reasonable quality for the purpose of routing light. Such holograms are often created using a pressing process that is not normally done in-house and is very expensive for small runs. We present a novel technique for the production of such holograms using a standard compact disk (CD) writer, which is fast and very cost effective, along with an analysis of results obtained using this technique.

Realtime hologram generation using iterative methods

This paper discusses the necessities for holograms to be generated in realtime for both telecommunications and video applications. Implications for implementing a fixed-point version of Direct Binary Search (DBS) in silicon studied, along with a more detailed look at the implementation and results collected for a realtime DBS method in a Field Programmable Gate Array (FPGA). The paper looks forward to future architectures and makes suggestions based on the trend of capabilities of FPGAs.
