Description:
We report on a proof-of-principle work aimed at the development of fast-response fiber-optic
accelerometers for seismic monitoring. The system is based on a semiconductor diode-laser
source that interrogates a newly devised two-dimensional inertial sensor suitable for
measurement of horizontal ground accelerations. Plane acceleration components of the
sensor’s mass are detected by two fiber Bragg gratings anchored to its structure. Calibration
and comparison with a commercial accelerometer are presented. A great potential, in terms of
frequency response and sensitivity, is demonstrated in view of possible field applications in
active seismic areas.
