A 1550 nm telemeter for outdoor application based on off-the-shelf components

Abstract : We will present at the workshop the development of a telemeter based on an intensity-modulated laser diode. It has the advantage to be more robust than classical fringe counting interferometers, especially for long-distance outdoor propagation, and less expensive than superheterodyne synthetic-wavelength interferometers [1]. For such a system, we aim a relative resolution of 10-7, i.e. some micrometers at short range or 100 ?m over 1 km.
