摘要： 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.

摘要： An optical fiber (22) of this invention is suitable for use in tethered vehicle. The optical fiber has a W-shaped refractive index configuration and is characterized by a .DELTA. of at least 0.9% and a cutoff wavelength of less than 1500 nm. Further, the refractive index configuration is such that a core (30) is characterized by a relatively high value of .DELTA..sup.+. The value of .DELTA..sup.+ is at least 0.6% for a single window of operation, whereas for a dual window it is 0.9%. Also, the refractive index configuration of the optical fiber is characterized by a depressed inner cladding portion (32) which has a .DELTA..sup.- of 0.3% and an outer radius about equal to the product of 2.5 and the radius of the core.
