Abstract :
We describe a fibre-optic accelerometer, based on the technique of nonlinear displacement-to-strain conversion (NDSC), suitable for use at DC and low frequencies. The sensor exhibits a minimum detectable acceleration of less than 1 μg RMS (g = 9.8 m/s2) at 0.5 Hz and a linear dynamic range greater than 106.
