Methods based on triangulation, time of flight, phase measurements and interferometry are used and will be further developed. Multiple wavelength interferometry allows the reduction of the sensitivity by a range extension leading to robust measuring systems. Superheterodyne interferometric techniques based on two wavelength heterodyne interferometry will also be discussed and experimental results will be shown.eninfo:eu-repo/semantics/openAccessInterferometrie , Laser , Triangulation530conferenceObject2012-06-11
