Abstract

Photon counting signals are often complex and can have multiple signature of different of types. The origin of these signatures may be, for example, objects that are not in the line-of-sight, light pulses that are traveling through the scene, and uncorrelated ambient light. Using computational imaging approaches, we are able to distinguish different signatures and we can reconstruct their origin. Non-line-of-sight imaging use back projection approaches to estimate the shape of hidden reflecting surfaces. Further, light-in-flight sensing is capable to track the path of light pulse moving in air and to trace back the laser pulse to its origin. Finally, photon flux imaging with ambient light illumination uses the temporal information of uncorrelated light to estimate the photon flux.
