Abstract: An apparatus and methods for measuring combustion parameters in the measurement zone of a gas turbine engine. The measurement zone is defined as being between an outer casing and an engine component having a reflecting surface inside the outer casing. The apparatus comprises a laser generating a transmitting beam of light of a select wavelength and a multimode transmitting fiber optically coupled to the laser. A transmitting optic is optically coupled to the multimode optical fiber for transmitting the beam into the measurement zone. The reflecting surface is configured to provide a Lambertian reflection. A receiving optic is positioned to receive the Lambertian reflection. Means are provided in operative association with the multimode transmitting fiber for averaging modal noise induced signal level variation of light propagating within the multimode transmitting fiber.

Abstract: A gas composition monitoring arrangement for a module 2 used in a solid oxide fuel cell comprises provision of an optically transparent window 4 in the end of a gas flow channel 3 formed in that module 2. Thus, the window 4 allows passive and active optical gas analysis of the gas flow through the channel in situ without the necessity as with previous systems of drawing a proportion of that gas flow away from the module 2 and therefore fuel cell for appropriate analysis. In such circumstances, actual in situ gas composition determination is achieved rather than a determination which may be distorted through the transfer regime to a previous remote gas analysis apparatus.

Abstract: Fiber-optic-based systems and methods for monitoring physical parameters using a remotely deployed circulator are disclosed. In a preferred embodiment the circulator is remotely deployed with respect to an optical source/detector and coupled thereto by two dedicated fiber optical cables: a forward line for passing light from the source through the circulator to fiber-optic-based sensors, and a return line for passing light reflected from the sensors through the circulator back to the detector. By using separate forward and return lines in conjunction with the circulator, backscattering phenomenon experienced on the forward line will not interfere with the reflected light signals coming from the sensors. The circulator, and hence the sensors, may therefore be remotely deployed from the source/detector present at a monitoring station, greatly expanding distances which optical sensing systems can span.

Abstract: A gas sensor using optical fiber technology to measure gas concentration in a test volume. In one embodiment, the sensor incorporates a gas enriching polymer which absorbs and concentrates carbon dioxide (CO.sub.2) from the test volume surrounding the sensor. The polymer is wrapped around the core of an optical fiber which guides radiation with first selected wavelengths to the polymer. The radiation propagates into the polymer and reacts with the carbon dioxide in the polymer. Determination of CO.sub.2 concentration in the test volume is made by measuring the amount of attenuation of the radiation after reacting with the carbon dioxide in the polymer. In another embodiment, the polymer is capable of absorbing oxygen from the test volume and oxygen concentration is measured using fluorescence quenching. Being added to the polymer, a special dye reacts to radiation having selected wavelengths and produces a second radiation with wavelengths which are different from the selected wavelengths and which are absorbed by oxygen. Determination of oxygen concentration in the test volume is made by measuring the degree of attenuation of the second radiation after reacting with the oxygen in the polymer.

Abstract: An optical fiber probe for attenuated total reflectance measurements comprises a tubular body within which pass input and output optical fibers. The optical fibers are mounted within the body so that radiation emitted from the end of one of the optical fibers can pass through the optical system of the probe and be reflected back and focused on to the end of the other optical fiber for transmission back to a spectrophotometer. The optical system includes an attenuated total reflectance element, preferably of zinc selenide, which has a cylindrical body having at one end two perpendicular cut-away surfaces to form a roof mirror and at the other end a convex surface which acts to focus the radiation on to the end of the output optical fiber. The material to be tested is allowed to come into contact with the surfaces of the roof mirror, and then radiation is sent through the element and is totally internally reflected within it. Sealing around the element is effected by means of an O ring seal which extends around the element's cylindrical surface. Since there are no internal reflections from this surface, the spectrum of the O ring is not picked up.
