A System, Device and Method for Detecting Seismic Acceleration

A device for detecting seismic acceleration including a proof mass; a base for providing a sensor acceleration, relative to the proof mass, based on the seismic acceleration; an optical fibre portion operatively connected between the proof mass and the base for providing a fibre tension based on the sensor acceleration, a fibre Fabry-Perot interferometer (FFPI) in the optical fibre portion for providing an optical characteristic representative of the fibre tension, and a compensator for applying a compensating tension to the FFPI to compensate for a change of the optical characteristic due to a temperature change of the FFPI.
