Diffractive optical computing

Artistic impression of optical computing performed by modulating the incident light with layers of diffractive structures, comprised of programmable liquid crystal array. A photodetector array then converts diffracted photons into electrons to realize a reconfigurable optoelectronic processor.

See Dai et al.
