Abstract

New experimental set-ups are presented which allow multidirectional analysis of inhomogene - ous phase objects by high resolution holographic interferometry. The applicability of these arrangements is tested in a first step. After this check of the method different kinds of plasmas are investigated. In order to obtain more sensitivity the techniques of resonance heterodyne holographic interferometry are applied. Knowing the relations between refractive index in the vicinity of a resonance line and the corresponding number density of ground state atoms this number density can be determined. 1.
