    摘要： A double-pass fiber-optic based spectroscopic gas sensor delivers Raman excitation light and infrared light to a hollow structure, such as a hollow fiber waveguide, that contains a gas sample of interest. A retro-reflector is placed at the end of this hollow structure to send the light back through the waveguide where the light is detected at the same end as the light source. This double pass retro reflector design increases the interaction path length of the light and the gas sample, and also reduces the form factor of the hollow structure.

    摘要： A first waveguide has a top face positioned in an oil well borehole for wetting by returning drilling mud from a drill bit as drilling progresses. A second waveguide is positioned in the borehole for wetting by new drilling mud being pumped to the drill bit. MIR light rays are fed from an MIR light source into the first and second waveguides for causing evanescent waves to be generated by each waveguide for reacting with the molecules of the associated drilling mud, respectfully, whereby a modulated optical signal representative of spectra of components and particles in the associated drilling mud, respectively, are emitted from each waveguide. The modulated optical signals are converted to electrical signals, subtracted from one another to remove common mode signals, and passed into a processor programmed for extracting the spectra hydrocarbon components contained in the returning drilling mud as the result of the drilling activity.
