A theoretical study is carried out in which a bare fiber optic cantilever beam, with no concentrated seismic mass, is proved to be suitable for measuring low-frequency vibrations accurately. Its behavior was experimentally verified in the laboratory and can be approximated by a very simple transfer function that leads to straightforward signal processing. Some practical configurations, with accuracies as good as 0.5%, are given that depend on the operating frequency range. The simplicity of the architecture is highlighted.
