Single-photon lidar for extreme imaging scenarios
Abstract
Single-photon detection when used in picosecond resolution time-correlated mode is now a candidate technology for a number of depth imaging applications in the visible, near-infrared and short-wave infrared regions. This approach has been used in a range of challenging sensing scenarios including imaging though highly scattering underwater conditions, free-space imaging through obscurants such as smoke or fog, and depth imaging of complex multiple surface scenes. I will review recent developments in this field and describe recent experiments and computational imaging approaches that highlight the long-term potential of this work.
