Space-variant holographic optical elements in dichromated gelatin.
TL;DR: A modified approach is suggested which allows for on-axis operation and replay in the near infrared and point to point, off-axis interconnects for replay at the recording wavelength (514.5 nm).

TL;DR: The construction of digital optical processors based on the cellular logic image processor (CLIP) architecture is discussed and a single-channel and a parallel version incorporating 256 information channels have been constructed.
Proceedings ArticleDOI
Space-variant interconnection networks in dichromated gelatin
TL;DR: In this paper, the authors demonstrate the design and fabrication of a number of space-variant holographic elements (SVHOEs) in Diffraction Efficient gelatin gelatin (Dcci), including a half cmssover, a perfect shuffle and several butterfly based networks.
Nearest neighbour spatially invariant reflection interconnect in dichromated gelatin
TL;DR: In this article, the authors report on the production and performance of a holographic nearest neighbor interconnect (NNI) recorded in dichromated gelatin (DCG) for use in a demonstration optical processor, discussed by A.C. Walker et al.
