Abstract

Although different computational techniques can provide impressive 3-D reconstructions of a hidden object, detecting an object out of the line of sight in real time with a portable system remains a major challenge. We recently presented a technique, based on single-photon counting, that can locate the position of an object hidden around a corner in a few seconds’ acquisition time, and that thus allows us to track its position as it is moving.
