An $80\times25$ Pixel CMOS Single-Photon Sensor With Flexible On-Chip Time Gating of 40 Subarrays for Solid-State 3-D Range Imaging

Autor: Lauri Hallman, Juha Kostamovaara, Henna Ruokamo

Publikováno v: IEEE Journal of Solid-State Circuits. 54:501-510

A CMOS solid-state 3-D range imager that uses short (~110 ps) laser pulses and a novel flexible time gating scheme for a single-photon avalanche diode (SPAD) array is presented. The array is divided into 40 subarrays for which a narrow ( $80\times25

Publikováno v: ESSCIRC

A solid state 3D scanner based on a pulsed laser diode source and narrow time gating of a 2D CMOS single photon avalanche diode (SPAD) detector array is presented. The imager uses an on-chip delay-locked loop to program the time gating of 40 sub-arra

A range-gated CMOS SPAD array for real-time 3D range imaging

Autor: Juha Kostamovaara, Lauri Hallman, Henna Ruokamo

Publikováno v: Electronic Imaging. 31:357-1

A range image of a scene is produced with a solid-state time of- flight system that uses active illumination and a time-gated single photon avalanche diode (SPAD) array. The distance to a target from the imager is measured by delaying the time gate i
