Abstract
Official abstract text for this publication.
Quantifying a refractive index of a test medium by obtaining spectral data representative for an optical signal being modulated with an optical transfer characteristics of a photonic sensor, the modulation being obtained by combining modulation of a first electromagnetic wave component in an optical filter element with a first periodic transfer spectrum having a first free spectral range and modulation of a second electromagnetic wave component in an optical filter element with a second periodic transfer spectrum having a second free spectral range being different from the first free spectral range. A relative is change induced in the second periodic transfer spectrum by bringing the test medium in proximity with the optical filter element with the second periodic transfer spectrum. The refractive index of the test medium is quantified by determining a wavelength offset of an envelope signal in said spectral data.
