摘要: We present the first 1Mpixel SPAD camera ever reported. The features 3.8ns time gating and 24kfps frame rate; it was fabricated in 180nm CIS technology. Two pixels have been designed with a pitch of 9.4$\mu$m 7T 5.75T configurations, respectively, achieving maximum fill factor 13.4%. PDP is 27%, median DCR 2.0cps, variation length 120ps, position skew 410ps, rise/fall <550ps, all FWHM at 3.3V excess bias. sensor used to capture 2D/3D scenes over 2m an LSB 5.4mm precision better than 7.8mm. Extended dynamic range demonstrated dual exposure operation mode. Spatially overlapped multi-object detection experimentally single-photon time-gated ToF for time.
