Open-loop fiber-optic gyroscopes (FOG's) are generally less stable than closed-loop FOG's, yet they offer simpler implementation. We propose a modification of the harmonic division algorithm for an open-loop FOG, which is more stable and also simpler for implementation than the original one. It is shown that when the analog signal is properly sampled and quantized, the performance of our algorithm reaches that of closed-loop FOG's. Our algorithm may be implemented by the use of off-the-shelf component, and does not require an integrated optics circuit.
开环光纤陀螺仪（FOG）通常不如闭环光纤陀螺仪稳定，但它们的实现更简单。我们提出了一种针对开环光纤陀螺仪的谐波除法算法的改进方法，该方法比原始算法更稳定且实现起来也更简单。结果表明，当模拟信号得到适当采样和量化时，我们算法的性能可达到闭环光纤陀螺仪的性能。我们的算法可以通过使用现成的组件来实现，并且不需要集成光学电路。
