Abstract
A corrosion sensor having a bean-splitting interferometer, a spectrometer and an analyzer, wherein said corrosion sensor is a contactless corrosion sensor configured to scan a sample comprising corroded and non-corroded areas, and further wherein said spectrometer collects Raman signatures from said sample, and said analyzer maps the corroded and non-corroded areas is disclosed. The corrosion sensor could be used for evaluation the degree of corrosion in the fuselage or engine of an aircraft, for example.
Claims20
A corrosion sensor comprising a beam-splitting interferometer, a spectrometer and an analyzer, wherein said corrosion sensor is a contactless corrosion sensor configured to scan a sample comprising corroded and non-corroded areas, and further wherein said spectrometer collects Raman signatures from said sample, and said analyzer maps the corroded and non-corroded areas.
A method for spectroscopic detection of corrosion in a sample, comprising generating a first beam comprising laser, striking the first beam in a scanning area of a sample comprising corroded and non-corroded areas to produce a second beam comprising a Raman signal, creating a phase delay in the second beam, passing the second beam through a spectrometer and analyzing the Raman signal of the second beam by an analyzer, wherein the spectrometer collects Raman signatures from the corroded and non-corroded areas, and the analyzer maps the corroded and non-corroded areas.
A method of manufacturing a corrosion sensor, comprising (a) locating a beam emitter that emits a first bean comprising laser, (b) locating a beam-splitting interferometer, (c) locating a spectrometer and (d) locating an analyzer within the corrosion sensor in a manner such that the beam strikes a scanning area of a sample and produces a second beam comprising a Raman signal, and the beam-splitting interferometer creates a phase delay in the second beam.
