Paper Abstract

Magnetic sensors have been used in applications ranging from keyboard switches to submarine detection. Recently developed fiber optic magnetometers promise to provide high performance/moderate cost alternative to existing sensors. The special properties of fiber magnetometers such as directional response, high sensitivity, room temperature operation are discussed in the context of other magnetometers. Fiber magnetometer design considerations, fabrication procedures, and performance measurements using magnetostrictive alloy coatings are presented. Optimum performance is obtained with a 36% - 64% nickel-iron alloy electroplated over the polymer jacket on a single mode fiber. Sensor designs for fiber optic magnetometers are shown.
