  • Fiber optic sensor for petroleum
    Patent number: 6184980
    Abstract: A silver halide fiber optic for the detection and identification of petroleum. The fiber optic serves both as a waveguide for transmitting a signal to and from petroleum in remote locations and also as an intrinsic part of the sensing element to obtain evanescent wave spectra. The evanescent wave is attenuated at various wavelengths based on the chemical composition of the petroleum in which the sensor is immersed. The spectrum obtained from an unknown sample is compared with the spectrum of known samples from a library to identify the unknown sample.
