Abstract
Directivity in magnetostrictive fiber-optic interferometric transducers was analyzed. Comparison was carried out theoretically and experimentally on cylindrical and racetrack transducers, and expressions were presented. The results show that the racetrack transducer has better performance both in sensitivity and directivity for it has a length of magnetostrictive strip in parallel to the measured field
