Abstract
An imager for time-resolved optical sensing was
fabricated in CMOS technology. The sensor comprises an array
of 128
/2 128 single-photon pixels, a bank of 32 time-to-dig-
ital-converters, and a 7.68 Gbps readout system. Thanks to the
outstanding timing precision of single-photon avalanche diodes
and the optimized measurement circuitry, a typical resolution
of 97 ps was achieved within a range of 100 ns. T o the best of
our knowledge, this imager is the first fully integrated system
for photon tim
