Secondly , the temperature characteristics of the sensor coil was researched . a temperature distribution model of the coil was found . according to the model a method for compensation for thermal - induced drift changes in the fiber optic gyroscope was proposed 其次,本文重點對光纖環(huán)的溫度特性進行了分析,得出了光纖環(huán)的溫度分布模型,并提出了一個光纖環(huán)溫度噪聲的補償方案。
