Paper Abstract

A theoretical concept and its experimental realization of a fiber-optic Bragg grating strain sensor system to measure dynamic deformations in rock masses are presented. The system has been designed in order to monitor strain variations in the range of 10-9 within a bandwidth of 0.1 to 2 kHz. First promising results from field experiments are shown where seismic signals have been detected, in comparison with conventional geophone registrations.
