Extrinsic Fabry–Perot interferometer vibration and acoustic sensor systems for airport ground traffic monitoring

Abstract

The authors describe new fibre optic vibrational and acoustic sensor systems developed for airport ground traffic monitoring. The theoretical background of the extrinsic Fabry–Perot interferometer (EFPI) sensors is derived, and results of laboratory experiments as well as initial field tests in an experimental surface movement guidance and control system (ESMGCS) at the Braunschweig airport are reported.
