Abstract:
A possible technique to measure absolute distances is presented. It is based on a Michelson interferometer where two tuneable lasers are superposed to create a very short synthetic wavelength. By exploiting relative and absolute interferometry theories merged together in a demonstrator experiment we have shown the possibility of absolute distance measurements with sub-fringe resolution.
