The U.S. Army needs a magnetometer capable of detecting magnetic anomalies as small as 0.1 gamma (10 -6 gauss) in the frequency range of <0.1 hz to 1.0 khz. Optical Technologies, Inc., proposes a fiber-optic magnetic sensor to meet this need. The sensor has the significant advantage of room temperature operation in a microminiature package. It has the following features: minimum magneitcfield anomalies detection capability of <-.1 gamma; frequency range from <0.1 to 1.0 khz; dipole directionality; permanent magnet (phase II version) to provide bias, thus minimizing power requirement; small probe volume; growth potential for multi-influence sensor operation; immunity to electromagnetic interference (EMI) and electro-magnetic pulses (EMP).
