摘要

本文报道了一种改进的基于驻波摆动效应的半球形谐振腔分频方法。首先，从理论上分析了驻波摆动效应及其测量方法。其次，通过仿真和实验对其进行了验证。最后，对实验结果进行了分析和讨论。实验结果表明，通过测量驻波摆动效应的周期，可以很容易地得到分频值。采用该方法，当Q因子为1.5 × 107时，分频值的分辨率可达0.0002Hz。该方法适用于测量高q半球形谐振器的超低频分裂。

Measurement method of frequency splitting for high- Q hemispherical resonator based on standing wave swing effect*

This paper reports an improved method of frequency splitting for hemispherical resonator based on the standing wave swing effect. Firstly, the standing wave swing effect and the measurement method are analyzed theoretically. Secondly, it is validated by simulations and experiment. At last, the experimental results are analyzed and discussed. The experimental results show that, the frequency splitting value can be easily obtained by measuring the period of the standing wave swing effect. Using this method, the resolution of frequency splitting value could reach to 0.0002Hz if the Q factor is 1.5 × 107. The method presented is suitable for the measurement of ultra-low frequency splitting for high-Q hemispherical resonator.
