  • Fuel cloud point or freeze point sensor with collinear optical geometry
    Patent number: 8753007
    Abstract: A system includes a sensing cell having a walled structure configured to receive a fuel sample within an interior space of the walled structure. The sensing cell also has at least one cooling surface located on at least a portion of the walled structure and configured to cool the fuel sample. The sensing cell further has an optical port configured to couple to one or more optical fibers and to provide first radiation to the fuel sample. In addition, the sensing cell has a mirror configured to reflect the first radiation in order to provide second radiation to the optical port. The optical port defines a collinear optical geometry for providing the first radiation to the fuel sample and receiving the second radiation through the fuel sample. The system also includes at least one cooler configured to cool the fuel sample in the sensing cell by cooling the at least one cooling surface.
