Indirect time-of-flight (iToF) cameras operate by illuminating a scene with modulated light
and inferring depth at each pixel by combining the back-reflected light with different gating …

The quest for accurate, high-resolution, low-power-consumption, and small-footprint 3D
depth cameras has driven a rapid improvement in Continuous-Wave (CW) Time-of-Flight …

This paper describes a 64× 64-pixel 3-D imager based on single-photon avalanche diodes
(SPADs) for long-range applications, such as spacecraft navigation and landing. Each 60 …

This paper presents a CMOS time-of-flight (ToF) range image sensor using high-speed lock-
