Fast-gated $16\times 16$ SPAD array with on-chip 6 ps TDCs for non-line-of-sight imaging

We present an array of
$16 \times 16$
single-photon avalanche diodes (SPADs) with 16 shared 6 ps time-to-digital converters (TDCs), designed for non-line-of-sight imaging. It features a timing jitter of 60 ps (FWHM), fast-gated capabilities and up to 1.6·10
⁸
photon time-tagging measurements per second.
