提出了一个实现多路多轴光纤陀螺仪的新方法。Ｎ个Ｓａｇｎａｃ干涉仪通过一个２×Ｎ耦合器共用一个光源。这些干涉仪都以通常的方波相位调制方法进行调制。不过，这些调制都在时间上有τ／Ｎ的延迟，τ是进入光纤环圈的平均传输时间。用一个简单的光电二极管探测从干涉仪返回的全部光信号，然后，再解调信号。该多路传输技术，既使在多个干涉仪中返回的功率不平衡的时候，对于产生一个恒定的偏值功率有重要意义。闭环配置允许远离截止频率的Ｎ个轴之间不产生交叉干扰。用两轴和三轴光纤陀螺仪证明了这一方法的性能。
A new method to realize multi-channel multi-axis optical fiber gyroscope is proposed. N Sagnac interferometers share a single light source through a 2 × N coupler. These interferometers are all modulated by the usual square-wave phase modulation method. However, these modulations have a τ / N delay in time and τ is the average transmission time into the fiber loop. A simple photodiode detects all the optical signals returned from the interferometer and then demodulates the signal. This multiplexing technique is important for generating a constant bias power even when the power returned in multiple interferometers is not balanced. The closed-loop configuration allows no crosstalk between the N axes far from the cut-off frequency. The performance of this method is demonstrated with two-axis and three-axis fiber optic gyroscopes.
