    • An optical fiber inclinometer comprises a pair of fiber Bragg grating devices, a fixed base, a connection plate, and a rotatable base. One end of the connection plate is fixed to the fixed base, whereas the other end of the connection plate is connected to the rotatable base through the joint of a turning pair mechanism between them. The two ends of each fiber Bragg grating device are installed onto the fixed base and the rotatable base respectively, and the two devices are mounted on the opposite side of the connection plate. Once the rotatable base rotates around the joint of the connection plate, axial tensile elongation occurs in one of the fiber Bragg grating devices, whereas axial compressive deformation occurs in the other device. The rotation angle of the rotatable base relative to the connection plate can be obtained by measuring and calculating the Bragg wavelength drifts of the pair of fiber Bragg grating devices respectively.
    • 光纤倾斜仪包括一对光纤布拉格光栅装置,固定基座,连接板和可旋转基座。 连接板的一端固定到固定基座,而连接板的另一端通过它们之间的转动对机构的接头连接到可旋转基座。 每个光纤布拉格光栅装置的两端分别安装在固定基座和可旋转基座上,两个装置安装在连接板的相对侧上。 一旦可旋转的基座围绕连接板的接头旋转,则在一个光纤布拉格光栅装置中发生轴向拉伸伸长,而在另一个装置中发生轴向压缩变形。 旋转底座相对于连接板的旋转角度可以通过分别测量和计算一对光纤布喇格光栅器件的布拉格波长漂移来获得。
