Abstract

This paper presents the results of a theoretical treatment of a method based on the use of a multiwave layout of a Fabry–Perot fiber interferometer that makes it possible to significantly increase the range of recordable displacements by comparison with a single-wave interferometer. The recording of the vibrations of the sensitive element of a vibroacoustic sensor whose amplitude is several times as great as the maximum possible for a single-wave interferometer is experimentally demonstrated.
