METHOD OF DETERMINING SENSITIVITY COEFFICIENT OF PERIMETER OF RESONATOR OF ZEEMAN RING LASER TO EFFECT OF LINEAR ACCELERATIONS Russian patent published in 2020 - IPC G01R29/00 

FIELD: measurement.

SUBSTANCE: invention relates to gyroscopes and measuring equipment and can be used to determine the sensitivity factor of the perimeter of the Zeeman ring laser resonator to the action of linear accelerations. In the disclosed method, a perimeter detuning signal is varied by varying voltages on the mirrors with piezoelectric motors, measuring the voltage difference U_λ/2 between minima of dependence of frequency of output signals of rotation sin and cos of voltage on piezoceramics, measuring frequencies of output signals sin and cos, annular laser is installed on vibration unit at amplitude of vibration acceleration A_acc, phase is smoothly changed ϕ₀ of generator and maximum of vibration drift is determined ΔΩ_Bmax at vibration frequency ν = 1/2T and ultimately determining the coefficient of sensitivity of the perimeter of the resonator of the Zeeman ring laser to the effect of linear accelerations.

EFFECT: technical result is to expand the field of application of the method and enable to determine the coefficient of sensitivity of the perimeter of the resonator of the Zeeman ring laser to the action of linear accelerations.
