Paper Abstract

Spectrally Resolved White Light Interferometry is used for real-time high-precision measurement of differential refractive index of low concentration solutions. Dispersion behavior of low concentration solutions is similar to that of their solvents, so that the differential refractive index is non-dispersive. White light provides redundant information which yields high precision results. Moreover, white light provides information about the absolute fringes' order, which allows to improve precision.
