The first Time-Of-Flight (TOF) 3D scanning systems were realized in the 1970s for military and space applications [1]. Both pulsed operation and CW modulation, either AM or FM, were used. Scanning systems have steadily improved in the following decades [2-4], evolving into commercial products for 3D metrology and modelling applications, although their cost remains high due to the requirements of the scanning mechanics.
