Absolute distance measurement with sub-fringe resolution
Author(s): N. Antonietti; A. Giugni; M. Pisani

Paper Abstract

A novel technique to measure absolute distances is presented. It is based on a Michelson interferometer where two tuneable lasers are superposed to create a synthetic wavelength. Relative and absolute interferometry theories are merged together. Its experimental realization allows absolute distance measurements with subfringe resolution. Preliminary results are presented in this work.
