SPS Distinguished Lecturer Presentation: First-Photon Imaging and Other Imaging with Few Photons

Co-sponsored by: EMBS (New Hampshire/Green Mountain/Maine Jt Chap,EMB18)

LIDAR systems use single-photon detectors to enable long-range reflectivity and depth imaging. By exploiting an inhomoheneous Poisson process observation model and the typical structure of natural scenes, first-photon imaging demonstrates the possibility of accurate LIDAR with only 1 detected photon per pixel, where half of the detections are due to (uninformative) ambient light.

The speaker will explain the simple ideas behind first-photon imaging. Then he will touch upon related subsequent works that mitigate the limitations of detector arrays, withstand 25-times more ambient light, allow for unknown ambient light levels, and capture multiple depths per pixel.
