Before revision: Principle of spectral reflectometry| Reflectometry can be either realised by 1: monitoring the shift of an extremum in x-direction via a spectrometer (BLI, RIfS), or 2: monitoring the change in intensity of one wavelength in y-direction via a photodiode or camera (SCORE) Principle The underlying principle corresponds to that of the Fabry-Pérot interferometer, which is also the underlying principle for the white-light interferometry.
