    Abstract: A method and a device for analyzing a structure by tomography and diffuse acousto-elastic field correlation are provided. An optical fiber comprising a plurality of measurement points of FBG (Fiber Bragg Grating) type, comprising sensors of Bragg grating type, is deployed in or on the structure to be analyzed. The method comprises the emission of light, into the optical fiber, and the measurement by correlation for each pair of FBG sensors. In a development, a prior imaging of the structure is performed by reconstruction of the velocities of propagation. Other developments comprise: the determination of the positions of the FBG sensors, the calibration of the tomography, the rosette configuration of the sensors forming the measurement points, the use of a plurality of optical fibers, of multiplexers, of lasers, of optical circulators, of omnidirectional optical sensors, of active noise sources, such as piezoelectric transducers, incorporated or not in the structure.

    Abstract: A reaction carrier (14), a measuring device (12) and a measuring method measure a concentration of gaseous and/or aerosol components of a gas mixture. A flow channel (42), extends between two connecting elements (44) and defines a reaction chamber (46) with an optically detectable reaction material (48) that reacts a component of the gas mixture or with a reaction product of the component. The reaction carrier (14) includes a temperature-measuring element (88). The measuring device (12) includes a temperature-measuring element (90) which records a temperature of the measuring device (12) and/or of the reaction carrier (14), and a temperature-determining unit (92) which determines the temperature of the gas mixture as a function of the measurement result of the at least one temperature-measuring element (90). The measuring method includes determining a concentration of the component on the basis of an optically detectable reaction and the determined temperature of the gas mixture.
