Abstract
An innovative fiber optic setup for the scattering–free absorption spectroscopy of liquids is presented. It makes use of an integrating sphere that contains the sample under test, coupled to a fiber optic supercontinuum source and to a fiber optic spectrometer. A collection of turbid lubricant oils was considered as a test case for verifying and validating the innovative scheme of diffuse–light absorption spectroscopy. Scattering–free spectra were successfully measured and processed as product fingerprints for the prediction of turbine types.
