Abstract

A fiber optic accelerometer exhibiting high sensitivity has been developed. The transduction element is configured optically as a Michelson interferometer. Mechanically it consists of a pair of liquid-filled mandrels wrapped with equal lengths of single mode fiber. Acceleration sensitivities in excess of 2000 radians/g are readily achieved. Such accelerometers have been employed as sensing elements in gradient hydro-phones that have been tested successfully both in the laboratory and in the field. The practicality of this accelerometer's design and operation is compared with that of other recently proposed fiber optic interferometric vibration sensors.
