摘要： A clamping device (300) for a light guide (112) is provided. The clamping device (300) includes a carrier structure having a first securing element (301) for securing the light guide (112) in a first position (401), and a second securing element (302) at a distance from the first securing element (301) for securing the light guide (112) in a second position (402), wherein the first and second positions (401, 402) have a first distance (403) in a longitudinal extension of the light guide (112). Further, an intermediate carrier (500) having a first surface (503) on which the first and second securing elements (301, 302) are attached in respective securing positions (501, 502), and an opposing second surface (504), which can be applied to a measurement object, is provided. Hereby, a second distance (505) of the securing positions (501, 502) of the securing elements (301, 302) on the intermediate carrier (500) is greater than the first distance (403) in a longitudinal direction of the light guide (112).

摘要： A curvature sensor includes a light source, a flexible light guide including cores, FBG sensors that are provided in the cores and constitute FBG sensor groups at predetermined positions along longitudinal axes of the cores. The curvature sensor includes a detector that detects an optical spectrum of light from the FBG sensors, and a processor that determines a bend position and a bend amount of the light guide. The FBG sensor groups include a first FBG sensor group and a second FBG sensor group next to it. FBG sensors in the first and second FBG sensor groups include gratings having first and second pitches. The first pitch is shorter than the second pitch and is closer to the second pitch than other pitches of gratings of FBG sensors that include gratings having pitches shorter than the second pitch.

摘要： An optical interrogation system, e.g., an OFDR-based system, measures local changes of index of refraction of a sensing light guide subjected to a time-varying disturbance. Interferometric measurement signals detected for a length of the sensing light guide are transformed into the spectral domain. A time varying signal is determined from the transformed interferometric measurement data set. A compensating signal is determined from the time varying signal which is used to compensate the interferometric measurement data set for the time-varying disturbance. The compensation technique may be applied along the length of the light guide.

摘要： A shape calculating apparatus includes a light source, an optical fiber provided with detection targets. The detection targets have mutually different light absorption spectra to decrease a quantity of light propagated by the fiber in accordance with a bend shape of the fiber. The apparatus also includes a light detector to detect light quantity information at wavelengths included in the light absorption spectra, a calculator to execute a calculation relating to a shape of each detection target based on the light quantity information. The apparatus further includes a setting change unit to change, with respect to each of the wavelengths, a dynamic range of at least either an intensity of light input to the optical fiber or an electric signal generated by the detector.

摘要： An accurate measurement method and apparatus using an optical fiber are disclosed. A total change in optical length in an optical core in the optical fiber is determined that reflects an accumulation of all of the changes in optical length for multiple segment lengths of the optical core up to a point on the optical fiber. The total change in optical length in the optical core is provided for calculation of an average strain over a length of the optical core based on the detected total change in optical length.
