In laser ranging highly integrated and mm-accurate micro-modules of pulsed time-of-flight laser radar realizations are being developed. The basis for the integration arises from the developed receiver and time interval measurement circuits. See, for example, the recent Minifaros project a (FP7-ICT-2009-4_248123, http://www.minifaros.eu) that aimed at the development of a generic laser scanner for perception in a vehicle environment.
