[Alp13] Two-mode interference measurement for nanometer accuracy absolute ranging
Revue Internationale avec comité de lecture : Journal optics letters, vol. 38(3), pp. 281–283, 2013, (doi:10.1364/OL.38.000281)Mots clés: telemeter laser interference nanometer-scale accuracy
Résumé:
We demonstrate a laser ranging scheme that uses a high-frequencymodulated beam to achieve subnanometer precision
by the combined use of interferometric and time-of-flight measurements.We first describe how the absolute distance is
extracted from a two-mode interference signal. In particular, we show that the signal, which presents both optical and
synthetic wavelength scales, allows one to achieve nanometer-scale accuracy, despite the significant long-term phase
drifts in the 20 GHz detection chains. We present results obtained with the telemeter implemented for a distance of
about four meters, obtained by folding the laser beam path to the target.
