Abstract
A modulation technique for 3D time-of-flight (TOF) cameras allows the operation of fully autonomous operated 3D TOF cameras. The method subdivides the exposure time into several sub-exposure intervals, for which the signal control unit adds a preferably pseudo-random common phase delay to the illumination and the sensor.
