集成光学光纤陀螺以其体积小、重量轻、以及高的调制频率与消光比引起了国际上的广泛重视。深入研究光纤陀螺的噪声特性，对于降低零漂是极为重要的。通过广泛调研，从光源、光纤环与集成光学芯片、电路、以及外界环境的角度，详细的论述了各噪声源产生的机理、特征和一些抑制噪声的办法。简要的提出了一种利用负反馈补偿零漂的方法
Integrated optical fiber optic gyroscope with its small size, light weight, and high modulation frequency and extinction ratio caused widespread international attention. In-depth study of the noise characteristics of fiber optic gyroscope, for reducing zero drift is extremely important. Through extensive research, from the perspective of light source, optical fiber ring and integrated optical chip, circuit, and the external environment, the mechanism, characteristics and some methods of noise suppression are discussed in detail. A method of compensating zero drift by using negative feedback is briefly proposed
