abstract

We present three types of intensity-based fiber-optic accelerometer with two axes of sensitivity. Transmission and reflection, or single-ended sensor configurations are compared and bare fibers or a machined brass element are used a seismic masses. The devices are shown to be capable of measuring accelerations at relatively low frequencies (below 1 kHz). Linear responses to acceleration were observed up to the limit of the testing apparatus and the crosstalk between vibration directions was always -12 dB or less.
