Abstract : A fiber optic transducer includes a fiber optic cable or ribbon, a sensor, fluid material for coupling the fiber optic medium to the sensor and an affixing material to optionally affix the position of the sensor position relative to the fiber optic ribbon by affixing only one end of the sensor to the fiber optic ribbon. The sensor can be made from either magnetostrictive or electrostrictive materials. The coupling fluid enables the transducers to be manufactured with substantially similar frequency responses across a range of frequencies.
