    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, relating to testing three-dimensional imaging systems. In some implementations, a system includes a mount for a three-dimensional camera, a mount for a calibration target, and a rail to which the mount for the calibration target is coupled. The movement of the mount for the calibration target is constrained to the direction extending along the rail. The system includes a processing device having logic that receives a reading from a particular three-dimensional camera coupled to the mount for the three-dimensional camera. The reading includes a distance from the three-dimensional camera to a particular calibration target coupled to the mount for the calibration target. The logic receives a measurement of an actual distance from the particular three-dimensional camera to the particular calibration target. The logic then provides measurement characteristics of the particular three-dimensional camera.

    Abstract: An apparatus is described that includes a pixel array having time-of-flight pixels. The apparatus also includes clocking circuitry coupled to the time-of-flight pixels. The clocking circuitry comprises a multiplexer between a multi-phase clock generator and the pixel array to multiplex different phased clock signals to a same time-of-flight pixel. The apparatus also includes an image signal processor to perform distance calculations from streams of signals generated by the pixels at a first rate that is greater than a second rate at which any particular one of the pixels is able to generate signals sufficient to perform a single distance calculation.
