Method for Determining the Modulation Coefficient of the Magnetometric System of a Quantum Rotation Sensor
https://doi.org/10.17586/0021-3454-2026-69-3-253-261
Abstract
The problem of choosing the modulation coefficient for the magnetometric system of a quantum rotation sensor in order to increase the signal-to-noise ratio during measurements is considered. Experimental results are presented that demonstrate the possibility of evaluating the quality of resonance in a quantum rotation sensor cell in two different ways: the classical laboratory method based on varying the modulation coefficient and analyzing the amplitude of the output signal, and the proposed method based on estimating the parameters of the magnetometric signal. There is also a comparison of the time spent on the implementation of each of the methods. Based on these studies, an approach has been developed to choose the value of the modulation coefficient, taking into account the current resonance quality in the system.
