Abstract

PURPOSE:To variably set up a magnetic resonance point at an optional point electrically near the resonance point and to improve measuring accuracy of absolute value of earth magnetism, by providing a simple means variably setting up a level of output signal of photodetector. CONSTITUTION:Variable gain amplifier are denoted by 11, 11'. Now, when this system is in some condition, it is operated in an angular frequency omega' by an output of a phase detector 7 and the other some means, for example, when it is found that the angular frequency in this system corresponding to a static magnetic field H0 is omega by a proton magnetometer rightly, the amplifiers 11 and 11' are regulated and each signal level is changed and it is made to operate the system at the point of omega. An absolute value of the static magnetic field can be continuously measured by the magnetometer accurately by carrying out such adjustment once. Further, three sets of the system shown in figure are arranged in three dimensions and each pair of the angular frequency can be set in the value approximate to omega by an omnidirectional magnetometer. Accordingly, it has an effect for decreasing a false signal at a restless time of the magnetometer for magnetic resonance of helium light.
