Abstract

Characterisation of fibre optic vibration sensors represents a challenge since they are not compatible with conventional data acquisition platforms. The situation is complicated by the difficulty of applying a well described input signal, e.g. in form of a precisely controlled acceleration level over a range of frequencies. For this, we have configured a system based on a precision vibration exciter driven by a vibration controller. Such a system is able to reproduce the sensitivity and frequency response of Bragg grating based accelerometers to a precision within a few percent.
