Enhanced zero-bias stability for angular velocity measurement based on an optoelectronic oscillator with
Abstract:
We propose and experimentally validate a simplified optoelectronic oscillator (OEO)-based angular velocity sensing scheme with time-division optical carrier switching. This scheme utilizes only a single OEO oscillation loop structure, where the wavelengths of two input lasers are matched to the two output ports of a delay-line interferometer, respectively. Consequently, when the magneto-optic switch toggles between the two wavelength carriers, the phase difference induced by the Sagnac effect generates opposite frequency shifts in the microwave signal generated by the OEO. Meanwhile, the identical OEO loop ensures common-mode suppression of environmental disturbances. Experimental results demonstrate that by performing beat-frequency detection on these oscillation signals, the zero-bias stability is improved by 74.2dB, reaching 1.36×10-2 °/s. The measurement sensitivity reaches 99.11 kHz/(rad/s). This system configuration is significantly simplified, enhancing its practicality and zero-bias stability.
