Universal linear processing of spatially incoherent light through diffractive optical networks

Information processing with light is a topic of ever-increasing interest among optics and photonics researchers. Apart from the quest for an energy-efficient and fast alternative to electronic computing for future computing needs, this interest is also driven by emerging technologies such as autonomous vehicles, where ultrafast processing of natural scenes is of utmost importance. Since natural lighting conditions mostly involve spatially incoherent light, processing of visual information under ...
