| description | PROBLEM TO BE SOLVED: To provide a method for calibrating an atomic functioning apparatus including electromagnetic coils by using optical pumping of a light beam.SOLUTION: The method for calibrating an apparatus including a light beam 2 passing through a cell 4 filled with helium to be optically pumped executes automatic calibration of electromagnetic coils 6, 7, 8 of an apparatus such as an atomic clock, a magnetometer or a gyroscope, by successively injecting current into the coils 6, 7, 8 and measuring a magnetic field induced in order to calculate transmission coefficients (magnetic field/current) of the respective coils 6, 7, 8 and actual angles formed by the coils 6, 7, 8 with extremely high accuracy. |
