METHOD FOR MEASURING THE EARTH'S MAGNETIC FIELD AND A QUANTUM MAGNETOMETER FOR IMPLEMENTING SUCH A METHOD Russian patent published in 2022 - IPC G01V3/14 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment, to quantum magnetometers with optical pumping, and can be used in geological exploration, archeology. The quantum magnetometer contains a semiconductor laser with a vertical structure, a chamber with alkali metal vapor and an optical multimode fiber, in accordance with the claimed technical solution, a semiconductor laser with a vertical structure is located in a secondary measuring transducer, which also contains a digital computer, a system for stabilizing the temperature of the chamber with alkali metal vapor, laser thermal stabilizer, laser current source, digital frequency synthesizer and analog-to-digital converter, alkali vapor chamber is located in the primary measuring converter, which also contains collecting lenses, a circular polarizer, a radio frequency coil that creates an additional field transverse to the optical axis, a chamber heater with alkali vapor metal and a photodiode, while the isotope Rb-87 is used as the alkali metal.

EFFECT: improving the accuracy of measurements.
