Holographic Computation on a Graphics Workstation

Mark Lucente

3-D full-color holographic images are rapidly generated using the computing power of the graphics rendering engine of a commercial workstation. Interactivity is less than 5 seconds and speed is likely to increase in the near future.


Diffraction-Specific Hologram Fringe Encoding

Mark Lucente

Two novel holographic encoding schemes, "Hogel-Vector Encoding" and "Fringelet Encoding", have been created for holographic bandwidth compression. Encoded fringes are compressed by factors of 16 and higher, and computation speeds have been increased by over a factor of 100. These novel encoding techniques are rooted in the spatial and spectral sampling of fringe patterns and their generation based on specified diffractive imaging tasks.

Minimum-Pixel Holograms

We are trying to understand the underlying information-theoretic limits to the content of holographic signals. These are being explored by ad hoc subsampling techniques intended to identify the key features of holographic information.
