Multi-Harmonic Modulation in a Fiber-Optic Gyroscope

Multi-Harmonic Modulation in a Fiber-Optic Gyroscope

Optimizing the bias modulation of a fiber-optic gyroscope is crucial to improving its precision. In this study, we propose and demonstrate the use of multiple harmonics of sinusoidal modulation as an intermediate alternative to the widely used modulation methods: sinusoidal and square-wave modulatio...
