Abstract
It is possible to improve the manner in which the chromatic dispersion of a sample (4) is determined. To this end, the sample (4) is irradiated in an interferometer (10), with the light of a radiation source (1). A downstream polarimeter (50) measures both the power changes and the polarization changes of the interference radiation. In the downstream evaluation unit (7) the wavelength-dependent chromatic dispersion can be determined.
