Patent number: 9910014Abstract: A method for the detection of a gas flowing from a location in a structure is described. A hollow-core optical fiber is placed in a position adjacent the structure. The fiber includes a sound-conductive cladding layer; and further includes at least one aperture extending into its cross-sectional diameter. A beam of pulsed, optical is transmitted into the fiber with a tunable laser. The optical energy is characterized by a wavelength that can be absorbed by the gas that flows into the fiber through the aperture. This causes a temperature fluctuation in the region of gas absorption, which in turn generates an acoustic wave in the absorption region. The acoustic wave travels through the cladding layer, and can be detected with a microphone, so as to provide the location of gas flow, based on the recorded position and movement of the acoustic wave. A related system is also described.Type: GrantFiled: December 22, 2015Date of Patent: March 6, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Niloy Choudhury, William Albert Challener

Patent number: 9823184Abstract: A distributed gas detection system includes one or more hollow core fibers disposed in different locations, one or more solid core fibers optically coupled with the one or more hollow core fibers and configured to receive light of one or more wavelengths from a light source, and an interrogator device configured to receive at least some of the light propagating through the one or more solid core fibers and the one or more hollow core fibers. The interrogator device is configured to identify a location of a presence of a gas-of-interest by examining absorption of at least one of the wavelengths of the light at least one of the hollow core fibers.Type: GrantFiled: May 13, 2016Date of Patent: November 21, 2017Assignee: General Electric CompanyInventors: William Albert Challener, Sabarni Palit, Jason Harris Karp, Ansas Matthias Kasten, Niloy Choudhury

Patent number: 9791619Abstract: Microstructured optical fiber (MOF) includes a cladding extending a length between first and second ends. The cladding includes an inner porous microstructure that at least partially surrounds a hollow core. A perimeter contour of the hollow core has a non-uniform radial distance from a center axis of the cladding such that first segments of the cladding along the perimeter contour have a shorter radial distance from the center axis relative to second segments of the cladding along the perimeter contour. The cladding receives and propagates light energy through the hollow core, and the inner porous microstructure substantially confines the light energy within the hollow core. The cladding defines at least one port hole that extends radially from an exterior surface of the cladding to the hollow core. Each port hole penetrates the perimeter contour of the hollow core through one of the second segments of the cladding.Type: GrantFiled: October 6, 2015Date of Patent: October 17, 2017Assignee: General Electric CompanyInventors: William Albert Challener, Niloy Choudhury, Sabarni Palit

Patent number: 9739706Abstract: A method for detecting of components in a fluid includes emitting a modulated light beam from a modulated light source to the fluid in a chamber, wherein the fluid comprises a liquid and a component in the liquid. The method includes producing an acoustic signal in response to the emitted modulated light beam and detecting the acoustic signal via a pressure sensor disposed in the chamber. The method in one example also includes transmitting the acoustic signal from the pressure sensor to a processor based module and determining at least one of a component and a concentration of the component in the fluid via the processor based module, based on the acoustic signal.Type: GrantFiled: August 25, 2014Date of Patent: August 22, 2017Assignee: GENERAL ELECTRIC COMPANYInventors: Sandip Maity, Nagapriya Kavoori Sethumadhavan, Niloy Choudhury
