Abstract

See full text

Method for measuring thickness of coatings includes illuminating an automobile sample comprising a substrate and at least one coating with light waves of varying wavelengths from a light source. It further includes receiving the light waves reflected by a top surface and a bottom surface of the coating on the sample at the light collector. It also includes diffracting the light waves into a plurality of component wavelengths with a grating, detecting light intensities of the plurality of component wavelengths at a detector array, generating a combined reflected interference pattern spectral curve using the detected light intensities for each of the received light waves for each of the plurality of component wavelengths, and calculating a thickness of the at least one coating from a frequency of the combined reflected interference pattern spectral curve of the component wavelengths.
