摘要
A method for measuring the thickness of coatings on a substrate of an aerospace component comprises illuminating a sample comprising the substrate of the aerospace component and a coating with light waves of varying wavelengths from a light source, receiving the light waves reflected by the sample at a light collector, diffracting the light waves into a plurality of component wavelengths with a grating, detecting the light intensities of the plurality of component wavelengths at a detector array, generating a reflectance spectral curve using the detected light intensities for each of the plurality of component wavelengths, calculating the thickness of the coating from the reflectance spectral curves of the component wavelengths.
