We describe a superparallel holographic optical correlator that performs two-dimensional spatial and angular multiplexing simultaneously. The key step in this architecture is the use of a holographic multiplexer to split a query image into many copies before it applies them to the holographic database. A holographic demultiplexer, in conjunction with an… (More)
Wayfinding in unfamiliar environments can pose a challenge to anyone, but can be especially challenging to someone who has some sort of visual loss.
