Demonstration of optical learning with luminescent materials for image classification

The benefits of using learning in computers is discussed. The advantages are described of using photonics over electronics for constructing learning systems. Optical devices are discussed, including a spatial light rebroadcaster (SLR) composed of a thin film of luminescing material which may be used to store dynamically changing weights during learning. An optical learning system is described that uses inner products computations with SLRs, and results of optical experiments are shown
