摘要： An industrial roll is provided, comprising a transverse force transducing fiber Bragg sensor that is embedded in the roll cover and/or located in-between the roll cover and the roll core of the industrial roll. The transverse force transducing fiber Bragg sensor comprises a fiber optical waveguide having a fiber core and a fiber cladding, and a stud element being nonpositively joined to a partial area of the circumferential surface of the fiber optical waveguide. The fiber optical waveguide comprises a Bragg grating located in the fiber core, whereby the dimension of the partial area in the longitudinal direction of the fiber is longer than a grating spacing of the Bragg grating. The partial area is located at a section of the fiber optical waveguide housing the Bragg grating, and at least a first component of the stud element is formed from a first material having a Young's modulus of less than 10 kN/mm2.

摘要： An arrangement for simultaneous optical determination of temperature and strain fluctuations in an optical fiber for precisely determining the changes in environmental influences and/or fiber loads is disclosed. The arrangement performs two different measurement tasks of the absolute measurement of a stationary quantity, such as temperature and the relative, high-resolution measurement of quickly varying quantities of fluctuation processes with comparable accuracy in a single optical The arrangement which is achieved using a spectrometer with an imaging, spectrally dispersive element, a first input light bundle being arranged with reference to the dispersive element such that the light spectrally dispersed at the dispersive element is projected onto a first linear receiver The arrangement, and an additional second input light bundle is directed onto the dispersive element in the spectrometer, whose spectrally dispersed light falls onto a second linear receiver The arrangement, parallel to the first one, the two input light bundles are fed light from a broadband light source which has been reflected by at least two optical fiber gratings with different mean wavelengths, and an interferometer The arrangement with phase modulation and different arm lengths is present at least in the light path of the second input light bundle upstream of the spectral dispersion by means of the dispersive element, whose evaluation is performed via the second receiver. The arrangement by means of phase modulation modules with reference to relative changes in the Bragg wavelengths, while a CCD evaluation module for determining the absolute Bragg wavelengths of the optical fiber gratings is arranged downstream of the first receiver The arrangement.

摘要： A small modulation current is applied to the light source of a Sagnac-type fiber optic gyroscope to increase accuracy and/or stability of scale factor (open loop configuration) and to reduce bias errors and random walk (closed-loop configuration). The phase and amplitude of the modulation current are controlled through a control circuit whose reference is picked off at a first beamsplitter in series with the light source. In such a way, light emitted from the light source into the interferometer contains no modulation. The elimination of modulation removes a source that would otherwise cause deterioration of gyroscope stability resulting from light returning from the interferometer or due to electrical interference, thus limiting measurement accuracy.
