论文摘要
基于SAGNAC效应的光学陀螺仪在应用高敏性惯性旋转传感器方面具有巨大的潜力。在本文中，我们证明，对于具有正常分散的光学共振陀螺仪，可以通过耦合到挤压的真空光中提高测量灵敏度两个数量级，这与经典情况下的情况不同。当系统在临界异常分散条件下操作时，注入挤压的真空光可以使测量灵敏度超过相应的标准量子限制，高出五个数量级，最小值为3.8*10^-5 Hz。这项工作为开发光学陀螺仪和尺寸很小的光学陀螺仪提供了一种有希望的可能性。
Optical gyroscope based on the Sagnac effect have excellent potential in the application of high-sensitivity inertial rotation sensors. In this paper, we demonstrate that for an optical resonance gyroscope with normal dispersion, the measurement sensitivity can be increased by two orders of magnitude through coupling into a squeezed vacuum light, which is different from that in the classical situation. When the system is operated under critical anomalous dispersion condition, injecting a squeezed vacuum light allows the measurement sensitivity beyond the corresponding standard quantum limit by five orders of magnitude, with a minimum value of 3.8*10^-5 Hz. This work offers a promising possibility for developing optical gyroscopes that combine high sensitivity with tiny size.
