    • A fiber Bragg grating (FBG) sensor is mounted to a rotating body, which is supported by a rotating shaft mounted rotatably with respect to a fixed element. The FBG sensor extends along the rotating shaft, one end of which is disposed at the center of the end of the rotating shaft. An optical fiber is mounted to the fixed element, one end of which is disposed opposite to the end of the FBG sensor, apart from the FBG sensor. Light emitted from a broadband light source passes through the optical fiber and is transmitted to the FBG sensor across a gap between the optical fiber and the FBG sensor. The FBG sensor reflects light with frequencies corresponding to deformation of the rotating body. A data processing unit receives the reflected light and calculates the deformation of the rotating body based thereupon.
    • 光纤布拉格光栅(FBG)传感器安装在旋转体上,旋转体由相对于固定元件可旋转地安装的旋转轴支撑。 FBG传感器沿着旋转轴延伸,其一端设置在旋转轴的端部的中心。 光纤安装在固定元件上,其一端与FBG传感器相对设置,与FBG传感器的端部相对。 从宽带光源发射的光穿过光纤,并通过光纤和FBG传感器之间的间隙传输到FBG传感器。 FBG传感器反射具有对应于旋转体的变形的频率的光。 数据处理单元接收反射光并据此计算旋转体的变形。

    • The present invention relates to a monitoring device for a rotating body, which can accurately measure signals from a fiber Bragg grating sensor provided on the rotating body by compensating a transmission loss variation and a distortion of the sensor signals. A rotation-side optical fiber has at least one deformation sensor at a portion thereof and a reference sensor at one end thereof. The sensors are made by forming a Bragg grating in the rotation-side optical fiber. A fixed-side optical fiber is mounted to the fixed body so as to be opposed to the one end of the rotation-side optical fiber. A signal processing unit detects a deformation of the rotating body by subtracting a signal corresponding to the light reflected from the reference sensor from a signal corresponding to the light reflected from the deformation sensor.
    • 本发明涉及一种用于旋转体的监测装置,其可以通过补偿传输损耗变化和传感器信号的失真来精确地测量设置在旋转体上的光纤布拉格光栅传感器的信号。 旋转侧光纤在其一部分具有至少一个变形传感器,其一端具有基准传感器。 传感器通过在旋转侧光纤中形成布拉格光栅而制成。 固定侧光纤被安装到固定体上以与旋转侧光纤的一端相对。 信号处理单元从对应于从变形传感器反射的光的信号中减去与从基准传感器反射的光相对应的信号来检测旋转体的变形。
