An apparatus and method for monitoring oxygen concentrations in fuel tank ullage comprising providing a sensor head comprising an optical cavity, exposing the optical cavity to an ambient gaseous environment of a fuel tank or air separation module, via a laser light source emitting wavelength modulated light through the cavity, and receiving the wavelength modulated light with a detector.
What is claimed is: 1. An apparatus for monitoring oxygen concentrations in fuel tank ullage, said apparatus comprising a sensor head comprising: an optical cavity exposed to an ambient gaseous environment of a fuel tank or air separation module, wherein said optical cavity is at least partially encased in a metal foam; a laser light source emitting wavelength modulated light through said cavity; means for expediting removal of liquid droplets from surfaces of said apparatus through which said wavelength modulated light passes; and a detector receiving ...
