A ToF-camera operates with modulated visible and near-infrared radiation, which is detected and demodulated simultaneously by a 2-D array of pixels. The phase shift between the sent signal and the received signal is an indicator for the object's distance. The amplitude of the radiation gives additional information for its reflectance. Unfortunately, measurements of distances performed with almost all cameras available on the market show very high deviations. The main reason for them seems to be...
