  • Patent number: 12313433
    Abstract: In the field of measuring physical parameters with a multimode optical fiber, a system for measuring P physical parameters at one or more measurement points has one or more multimode optical fibers. The system includes: a light source generating a source optical signal, a multimode measurement optical fiber transporting optical signals in at least M distinct second predetermined propagation modes, M being an integer greater than or equal to P, the measurement optical fiber including a measurement section reflecting the optical signals with a wavelength variable according to physical parameters to be measured, a detection device measuring wavelengths of the optical signals reflected by the measurement section, and an optical module generating M signals from the source optical signal, the M signals each being injected into the measurement optical fiber to propagate in one of the modes, the optical module also transferring the optical signals reflected toward the detection device.

  • Patent number: 12044566
    Abstract: A measuring device including a measuring equipment that is configured to be optically interrogated by a measuring instrument with first optical signals in a first wavelength range, and a connecting optical fibre for optically connecting a measuring equipment to a measuring instrument. The connecting optical fibre includes at least a first optical core that is multimode in the first wavelength range and a second optical core that is single-mode in a second wavelength range. The connecting optical fibre includes at least one first segment of functionalised optical fibre that is such as to exhibit, at the second wavelength, and optical property that varies with an environmental parameter of the connecting optical fibre. The invention also relates to a measuring assembly and to an apparatus that includes such a measuring assembly.

  • Publication number: 20240240973
    Abstract: A spectral interrogation device, including: an optical source for emitting a light signal, a measurement optical fibre comprising a series of successive Bragg gratings for reflecting the light signal in different wavelength bands, a reflective optical fibre comprising a total reflection element, a wavelength detector, and an optical switch for switching between a sequence of three operating modes. In a first mode, the light signal emitted by a given optical source is guided from the optical source to a corresponding measurement optical fibre. In a second mode, the light signal is guided to make a predetermined number of return trips in a line formed by a coupling between the measurement optical fibre and a corresponding reflective optical fibre, generating a predetermined delay between the successive gratings. In a third mode, the light signal is guided to a corresponding detector to successively measure the wavelength bands associated with the gratings.

  • Patent number: 9291779
    Abstract: The connection device for liquid-core optical fiber comprises a sleeve traversed by a channel comprising a plurality of communicating stacked conduits, a first conduit being formed from an end of the sleeve and being arranged to receive, in a sealed manner, at the corresponding end of the sleeve, one end of the optical fiber, and a second conduit being formed communicating with the first conduit, and closing means that hermetically seal the end of the second conduit opposite the end that communicates with the first conduit, the sleeve further having a third conduit for filling the internal volume of the second conduit when the latter is closed at one end by the closing device and the fiber is inserted into the first conduit, the third conduit transversely connecting the outside of the sleeve with the inside of the second conduit, and a sealing plug for hermetically sealing the port of the third conduit opening to the outside of the sleeve.

  • Publication number: 20100290062
    Abstract: The invention involves a sensor (100) with a Bragg network fiber including a source (105) and detection system (101), operating at a wavelength of a given study, in addition to a Bragg (6) network fiber (1) linked to said source and said system, with said fiber being a microstructured optic fiber whose sheath (5) includes channels (3) adjacent to the heart (2) of the fiber (1), capable of receiving a product to be analyzed, characterized in that the number of channels (3) adjacent to the heart (2) is between 2 and 5, and that the size of the heart (2) of the fiber (1) is adapted so that an electromagnetic field of a wave guided by the fiber is not confined in the heart (2) of the fiber (1), and the electromagnetic field extends into the channels (3).
