PROTON PRECESSION MAGNETOMETER SENSOR MEASURABLE IN ALL DIRECTION

摘要

PROBLEM TO BE SOLVED: To provide a proton precession magnetometer sensor capable of all-direction measurement, in which measurements is possible in all directions since there is no low-sensitivity angle (dead band).;SOLUTION: The present invention relates to a proton precession magnetometer sensor capable of all-direction measurement, in which the frequency of a current induced in a coil by streaming and then breaking the current in the coil is measured to calculate the strength of an external magnetic field. The coil may be achieved by two solenoid coils connected perpendicularly, or N solenoid coils connected in the form of a polygon, where N is an integer of 3 or more.;COPYRIGHT: (C)2012,JPO&INPIT
