  • Patent number: 12235140
    Abstract: An apparatus for digitizing an optical signal comprises: an optical detector to detect an optical signal and to generate an electric signal corresponding to the optical signal; an envelope curve detector to determine the amplitude of the electric signal or a modified electric signal resulting from the electric signal, and to supply an amplitude signal corresponding to the amplitude; an analog to digital converter to digitize the amplitude signal and to supply a corresponding digitized amplitude signal; and a variable voltage source to calibrate the envelope curve detector.
    Type: Grant

  • Publication number: 20250020492
    Abstract: An apparatus for the spatially resolved measurement of a physical quantity comprises a first optical fiber for the spatially resolved measurement and a first laser light source for generating laser pulses. The apparatus is configured such that the laser pulses are coupled into the first optical fiber, the laser pulses in the first optical fiber generate signals which are usable for measuring the physical quantity by backscattering and/or reflection, and the signals generated are coupled out of the first optical fiber. The apparatus further comprises an evaluation device configured to determine the physical quantity to be measured in a spatially resolved manner from the signals coupled out, and a second laser light source for generating pump laser radiation in continuous-wave operation. The pump laser radiation causes amplification of the laser pulses and/or of the signals generated in the first optical fiber.

  • Patent number: 11469816
    Abstract: A distributed sensing apparatus based on Optical Time Domain Reflectometry, OTDR, including an optical source; an optical splitter in optical communication with the optical source, the optical splitter having first and second outputs; a sensing fibre in optical communication with the first output of the optical splitter; a combining unit arranged to combine a reference signal derived from the second output of the optical splitter with a backscattered signal derived from the sensing fibre, wherein the combining unit comprises one or more 3×3 fused fibre couplers; and a signal processing unit configured for processing information derived from the combining unit so as to provide distributed sensing data. The combining unit includes a polarization diversity arrangement including one or more polarization sensitive elements.
