The detector used had an efficiency of 18{\%} at 1 kHz dark count rate, and the overall system jitter was {\textasciitilde}100 ps. The depth images were acquired by illuminating the scene with an optical output power level of less than 250 {\textmu}W average, and using per-pixel dwell times in the millisecond regime.", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=1053), last updated on Wed, 18 May 2016 15:26:18 -0500", doi="10.1364/OE.21.008904", opturl="https://doi.org/10.1364/OE.21.008904" }
