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 incoherent light is crucial for various imaging and sensing applications. Additionally, state-of-the-art microscopy techniques for high-resolution imaging at the micro- and nano-scale also depend on spatially incoherent processes such as fluorescence light emission from specimens.
