Abstract
We present a fibre optical accelerometer based on a balanced double cantilever design that offers improved performance in terms of sensitivity, frequency range and reliability in general. Within a three year project funded by the Danish National Advanced Technology Foundation, we have developed a rugged prototype with a wavelength sensitivity of 20 pm/g within ±1dB over a frequency range from DC to 1 kHz. These units are currently undergoing field tests in monitoring applications, e.g. for wind turbines, energy services, aerospace etc. In particular, we consider sensitive and reliable accelerometers essential for future condition monitoring and structural health monitoring applications.
