A device for optical fibers for measuring physical magnitudes such as the position, speed, the force, the pressure and other similar magnitudes

摘要

P the invention relates to the optical measuring devices. A device for measuring physical magnitudes such as the speed, acceleration, the force, etc, comprises at least one optical fiber 5 which conveys the light between an electronic assembly e and a transducer g. the latter comprises an optical modulator which modulates the light emitted by the transducer as a function of the quantity to be measured. The transducer g comprises at least one optical filter which generates a signal of the stabilization and possibly a measurement signal in one or several ranges of wavelengths. Application in the measuring instruments. / p
