Studies on a dispersive Michelson interferometer

Abstract

Abstract

Dispersive Michelson Interferometer (DMI) has the common configuration of Michelson Interferometer (MI) invented by Albert Abraham Michelson in 1881, where a transparent dispersive medium is added to the optical path of MI. Different types of fringes can be observed with different light sources ( monochromatic, quasimonochromatic and white light source) are applicable.

This interferometer can be used for measuring refraction and dispersion of different variety of samples and it has many applications in the fields of metrology, spectroscopy, internal and external topography. In this work a modification of the original interferometer is introduced. The two mirrors are movable and a holder for samples is added. Refraction and dispersion of solid glass samples (BAK1, BK7, N-LAF35, SK4 and Carl Zeiss) of thicknesses (12.101, 12.473, 9.930, 6.602 and 12.250 mm) are measured.
