Abstract: This letter presents an optical method of excitation for a 3-D fused silica dual-shell resonator. Modulated light from a 980-nm laser diode was directed at the rim of the hemispherical ...

Abstract: Accurate detection and excitation of standing wave on resonator are crucial for achieving Rate-Integrating Hemispherical Resonator Gyro (RI-HRG). The imbalance electrical characteristics ...
