Fibre-Optic System for Rotational Events&Phenomena Monitoring

It’s mobile, based on a Sagnac interferometer, a fibre-optic system for monitoring (via Internet or GSM) rotational events and phenomena (in detection bandpass 0.01 -100 Hz). The device is optimized for measurement of the rotational rate with a resolution in the range of < 50 nrad/s for 1Hz detection bandpass. The above-mentioned sensitivity, as well as bandpass, fulfill expected rotational events and phenomena connected with irregular object movements existing during strong winds, tectonic moves, and earthquakes. In this way, the development system is dedicated to monitoring the rotational vibration exiting in such objects as wind power plants, high irregular buildings, bridges, and troubled grounds.

The project has been developing since 2002, first in Military University of Technology with partnership with m-Soft Sp. z o. o. In the period 2021-2023, Elproma Electronics developed the 6th generation of FOSREM sensors under project POIR.01.01.01-00-1553/20-00 “FOSREM—from Sky across Ground up to Underground.” Since 2024, Elproma Electronics has been developing an innovative distributed structure based on the FOSREM under project FENG.01.01-IP.02-1714/23 “FOM-MEM – Fiber-Optic Matrix for Mechanic al Events Mapping“.
