Lookup-table-based time-bin correction for SPAD arrays in non-line-of-sight imaging
Single-photon avalanche diode (SPAD) arrays operated in time-correlated single-photon counting (TCSPC) mode are key enablers for non-line-of-sight (NLOS) imaging [1], yet manufacturing tolerances in their on-chip time-to-digital converters (TDCs) [2] introduce pixel-dependent timing errors that degrade reconstruction q...
