Abstract

The undesirable dynamic effects of harmonic vibrations due to various devices and technologies are commonly monitored using by seismic stations operating on the principle of mechanical vibration systems (using on horizontal foundation structures or rock mass) or by resistance strain gauges (using e.g. on vertical concrete or steel elements). Modern, progressively evolving alternative to monitor these dynamic effects are methods based on fiber-optic principle. There is used fiber Bragg grating (FBG) or fiber-optic interferometric sensors. At the experimental level the article presents results comparison of conventional approaches to the monitoring of harmonic vibrations and approaches based on fiber-optic principle. Data was process in both amplitude and frequency domain.
