Résumé:
We are developing a telemeter based on the measurement of the phase
accumulated by a RF sine wave during its propagation in air. This wave is
carried by a laser beam thanks to an intensity modulation. The main
limitation of this technique lies in amplitude-to-phase conversion occurring
in the detection of this modulation. Therefore, we characterized in this
paper this phenomenon for a given telemetric system and discuss on how
to reduce its effects on the resolution and the accuracy of the distance
measurement. Finally, a solution is implemented and tested outdoor, in
real conditions of use.
