Abstract: The invention relates to a fiber optical measuring device with a transducer section (5, 6, 7) comprising an optically supplied electronic system (7), the supply power and the measuring signal being arranged to be transmitted on the same light guide fiber (4), the device comprising light-emitting diodes (2,5) and photo-diodes (3, 6). The invention is characterized in that the light-emitting diode (5) for transmission of the measuring signal is transparent to the light wavelength (λ 1 ), which is used for supplying the photo-diode (6) for the power supply, and that this light-emitting diode (5) is located in the optical path between the end of the fiber (4) and the photo-diode (6) receiving the optical supply power, and/or that the photo-diode (3) for receiving the measuring signal is transparent to the light wavelength (λ 1 ) that is used for the supply power, this photo-diode (3) being positioned between the other end of the fiber (4) and the light-emitting diode (2) which emits the supply power. The Invention allows the use of the same light guide fiber (4) for transmitting the measuring signal and the supply signal without the need for fiber branches.

Abstract: The invention relates to a fibre optical measuring device with a transducer section (1-5) comprising an optically supplied electronic circuit (1) and/or transducer elements which require excitation energy, the supply power and the excitation energy being transmitted on the same light guide fibre as the signal information (measuring signal). The invention is characterized in that the signal information is arranged to be transmitted to a receiver location in the form of light which is emitted from the transducer section (1-5) when optically excited charge carriers recombine within a semiconductor material in the transducer section, and that this recombination is arranged to be controlled by electric signals (2-4).
