OPTICAL FIBER MAGNETO OPTIC FIELD SENSOR |
摘要 |
<p>An apparatus and system, capable of measuring the magnitude and direction of magnetic fields including an ultra-sensitive, wideband magneto optic (MO) sensor having magneto-optic crystals is disclosed herein. The sensor exploits the Faraday Effect and is based on a polarimetric technique. An ultra sensitivity optical-fiber magneto-optic field sensor measures a magnetic field with minimal perturbation to the field, and the sensor can be used for High-power microwave (HPM) test and evaluation; Diagnosis of radar and RF/microwave devices; Detection/measurement of weak magnetic fields (e.g., magnetic resonance imaging); Characterization of very intense magnetic fields (>100 Tesla, for example rail gun characterization); Detection of very low-frequency magnetic fields; Characterization of a magnetic field over an ultra broad frequency band (DC—2 GHz); Submarine detection; and Submarine underwater communication.</p> |
