A measurement system based on a single-mode fiber optic interferometer has been developed to simultaneously measure the vibrations in terms of velocity. The fiber interferometer reported has been realized with the purpose of using it as the basic measuring sensor of the system. One of its main features is that it is operated in the homodyne mode allowing the detection of the direction of motion without using Bragg cells or other optical or mechanical shifting devices, which usually present different inconveniences. The sensor has been calibrated against a commercial laser vibrometer. The first system prototype developed and presented in this work is capable to measure the vibration on two points simultaneously.

Abstract

A measurement system based on a single-mode fiber optic interferometer has been developed to simultaneously measure the vibrations in terms of velocity. The fiber interferometer reported has been realized with the purpose of using it as the basic measuring sensor of the system. One of its main features is that it is operated in the homodyne mode allowing the detection of the direction of motion without using Bragg cells or other optical or mechanical shifting devices, which usually present different inconveniences. The sensor has been calibrated against a commercial laser vibrometer. The first system prototype developed and presented in this work is capable to measure the vibration on two points simultaneously.
