To be transmitted by optical fibers and according to a coding device, the value of a magnitude for measuring a physical variable and device for implementing this process

摘要

To transmit a variable physical magnitude of the measurement of a sensor mesure11 has an apparatus for evaluation10 issuing characteristics of the signals to display this value by means of a fiber optique13 and by the use of a source of lumiere14, two streams lumineuxi, i produced by a filtre15 a capteur11 are injected in the appareil10 by means of the same fiber optique13, these streams possessing of the light powers, the spectral distribution of the various structures in the form of a narrow band, reciprocally nested together of the spectral point of view, and which are measured. / p & & p & application in particular to the sensors for measuring the electrical, the medicine and the automobile construction.
