Iterating the Transient Light Transport Matrix for Non-Line-of-Sight Imaging
A SPAD array captures the full first-order transient light transport matrix of a relay wall, and beamforming algorithms extract the second-order transient light transport matrix of the hidden scene, enabling relighting, direct/indirect separation, and dual photography.
