METHOD FOR REDUCTION OF MAGNETIC DRIFT OF ZEEMAN LASER GYROSCOPES

摘要

FIELD: instrument engineering.;SUBSTANCE: invention relates to instrument-making and can be used in creation of Zeeman laser gyroscopes. Method for reducing magnetic drift of Zeeman laser gyroscopes comprises steps of creating a field which compensates the sum of constant magnetic fields acting on the Zeeman laser gyroscope by direct current supplied to the coil surrounding the gas-discharge gap of the Zeeman laser gyroscope, wherein the value of direct current, which is supplied to the coil surrounding the gas-discharge gap of the Zeeman laser gyroscope, is set equal to 19 mcA.;EFFECT: high sensitivity and accuracy of Zeeman laser gyroscopes in conditions of thermomagnetic drift.;1 cl, 3 dwg
