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 (ToF) technology. Commercially available 3D image acquisition techniques include Stereo Vision, Structured Light, and ToF. CW ToF imaging systems offer excellent mechanical robustness, no baseline requirement, high effective depth image resolution, low computational cost, and simultaneous IR ambient light invariant intensity capture (Active Brightness). In a CW ToF camera, light from an amplitude modulated light source is backscattered by objects in the camera's field of view, and the phase delay of the amplitude envelope is measured between the emitted and reflected light. This phase difference is translated into a distance value for each pixel in the imaging array.
