Abstract

We present an experimental system which allows recording of the dispersion curve n= n(σ) of a sample,n being the refractive index and a the wavenumber . The system consistsicin a Michelson interferometer in one of whose arms the sample is placed. A white light source ( Xe 150 watt ) is used to illuminate the interferometer. A spectroscopic de-vice is placed in series with the interferometer in order to get the channelled spectrum produced by the sample. The intensity distribution 1(a). 21o(1+cos2rane) stores the function n(a) .
