摘要： In a sensor arrangement for sensing temperature and strain, an optical fiber with a Bragg grating therein is arranged on a substrate and embedded in a cover layer. The fiber is initially adhered onto an adhesive carrier, which then positions and applies the fiber onto the substrate. The fiber is point-wise fixed onto the substrate by a binder applied through holes in the adhesive carrier. Next, the carrier is stripped off to leave the fiber on the substrate. A cover layer is applied over the fiber and the substrate. Temperature and strain variations are transmitted from the cover layer into the fiber as non-circularly-symmetrical strains. The strain and temperature can be independently determined using this single sensor, by feeding quasi-depolarized light into the fiber and measuring the overlapping birefringent reflections from the Bragg grating. The full width at half maximum value indicates the temperature, while the Bragg wavelengths indicate the strain and the temperature.

摘要： An arrangement for determining measured values, in particular measured pressure values, strain values, or temperature value, using a plurality of optical fiber Bragg grating sensors. The optical fiber Bragg grating sensors are combined to form various arrays of optical fiber Bragg grating sensors that are arranged one behind the other, are connected by fiber optics, and exhibit different frequency selectivities. Delay elements are assigned to these arrays. The Bragg grating sensors receive a uniform query signal representing a time-differentiated, frequency-selective light. The frequency-selective Bragg grating sensors of the various arrays generate partial signals. The partial signals, separated temporally from one another by the delay elements, form a sequence of partial signals. From the knowledge of the propagation delays of the signals and from the knowledge of the frequency information of the query signal, the particular intended measured value is able to be related to a specific Bragg grating sensor of a specific array, thereby enabling the measured value to be allocated to the location of this Bragg grating sensor.

摘要： A device for applying light conductive fibers onto substrates and having a mounting yoke, a holding device and a stamping device. The holding device is configured as a U-shaped base body with an upward arching outside area having guide grooves and holders for installing the fibers in the device. The stamping device consists of a stamp, a stamp neck and a stamp head, which are inserted and linearly guided in the U-shaped die sink in the holding device. The device ensures a precise positioning of fibers and in particular of functional units in fiber segments. Fiber breaks can be nearly ruled out with the application method. The separating foils ensure that the device can be removed after the adhesive has hardened, so that no force is exerted onto the fiber through excess adhesive that sticks.
