Abstract: A fiber optic sensor system employs at least one light source that operates to generate light having one or more desired wavelengths. A first optical fiber based sensor transparent to a desired light wavelength operates to sense a magnetic field emitted from a predetermined electrical conductor or a current flowing through the electrical conductor. A temperature sensor that may be another optical fiber based sensor operates to sense an operating temperature associated with the first optical fiber based sensor in response to the light generated by the light source. Signal-processing electronics adjust the sensed current to substantially compensate for temperature induced errors associated with the sensed current in response to the measured operational temperature of the fiber optic sensor.

Abstract: A waveguide (116) fabrication method includes depositing a photodefinable copolymer material (14) comprising methyl methacrylate, tetrafluoropropyl methacrylate, and an epoxy monomer; fixing optical elements (10, 12) relative to the copolymer material; sending light through at least one of the optical elements and copolymer material towards the other; volatilizing uncured monomer. Another waveguide (116) fabrication method includes: fixing optical elements (110, 112) relative to each other, each having an optical surface (11, 13); providing a copolymer blob (114) over the optical surfaces with sufficient surface tension to result in the copolymer blob having a curved surface (15); sending light through each of the optical elements towards the curved surface and the other; volatilizing uncured monomer. An optical path fabrication method comprises: fixing optical elements (70, 76) relative to each other, each having an optical surface (71, 77); translating and rotating a mirror (78) until aligned to optimally direct light from one of the optical elements to the other; securing the aligned mirror in position.

Abstract: Ein Gasnachweissystem (100) zum Identifizieren eines Gases (12) wird angegeben. Das Gasnachweissystem (100) schließt ein Anzeigemodul (10) mit einer hohlen Kammer (14) ein, die von einem Kammergehäuse (16) eingeschlossen ist. Das Anzeigemodul (10) schließt eine optische Anzeigefaser (18) ein, die innerhalb der hohlen Kammer (14) angeordnet ist. Die optische Faser (18) schließt einen Gassensor (20) mit einem Bragg-Fasergitter (20), das an einer Gitterstelle (26) entlang der optischen Anzeigefaser (18) angeordnet ist, und eine Anzeigeschicht (32) ein, die an einer äußeren Oberfläche (38) der optischen Anzeigefaser (18) an der Gitterstelle (26) befestigt ist. Nach dem Eintreten des Gases (12) in die hohle Kammer (14) tauschen die Anzeigeschicht (32) und das Gas (12), teilweise auf der Grundlage eines Wärmeübertragungs-Koeffizienten des Gases (12), Wärmeenergie aus. Der Austausch der Wärmeenergie induziert eine Verschiebung in einer Bragg-Resonanzwellenlänge des Bragg-Fasergitters (20), die eine Schwellenverschiebung übersteigt, die für den Nachweis erforderlich ist, wobei die Verschiebung zum Identifizieren des Gases (12) benutzt wird.

Abstract: Es wird ein System für die Überwachung einer relativen Verschiebung eines Paares von Wickelkopfkomponenten bereitgestellt. Das System enthält eine auf den Wickelkopfkomponenten befestigte Struktur. Das System enthält ferner ein auf einer nicht-gekrümmten Oberfläche der Struktur befestigtes Faser-Bragg-Gitter, wobei das Faser-Bragg-Gitter dafür konfiguriert ist, einfallende Strahlung mit einer Spitzenintensität bei einer entsprechenden Wellenlänge auf der Basis einer Zugspannung des Faser-Bragg-Gitters zu reflektieren. Die Struktur ist so konfiguriert, dass die von der Struktur erzeugte Zugspannung eine Größe der Zugspannung des Faser-Bragg-Gitters auf einen vorbestimmten Bereich über eine Spanne der relativen Verschiebung des Paares der Wickelkopfkomponenten begrenzt.

Abstract: The system includes a structure 110 mounted to the end-winding components 102, 104. The system further includes a fiber Bragg grating 116 mounted to a non-curved surface 126 of the structure, where the fiber Bragg grating is configured to reflect incident radiation having a peak intensity at a respective wavelength based on a strain of the fiber Bragg grating. The structure is configured so that the strain produced by the structure limits a magnitude of the strain of the fiber Bragg grating within a predetermined range over a span of the relative displacement of the pair of end-winding components.
