Behavior of Signal from Optical Circuit of Quantum Rotation Sensor Based on Nuclear Magnetic Resonance

Resumo

The paper considers a common operation principle of a quantum rotation sensor based on nuclear magnetic resonance, giving a semi-classical description of processes in the sensor circuit, that is useful for obtaining the analytical representation of a signal at the optical circuit output. The principles of numerical calculation are briefly presented for an optical signal of the rotation sensor based on a one-dimensional quantum model. Comparison of calculations according to classical model and more stringent quantum model has shown that the sensor signal has a more complicated structure than that following from the classical description which shows only some properties of dynamic processes in the circuit. The results are important for the development of methods for demodulating the quantum rotation sensor optical signal and for estimation of expected characteristics of practical devices.
