DETERMINATION OF PARTICLE DENSITIES AND LINE-PROFILES IN PLASMAS BY RESONANCE INTERFEROMETRY - A FEASIBILITY STUDY USING COMPUTER-SIMULATEDREFRACTIVITY DATA

The principles of resonance interferometry are described with regard t o two applications: High accuracy particle density determination withi n plasmas and interferometrical determination of spectral line profile s. The usability of this technique is investigated numerically, and ph ysical limits are given for the regions in which resonance interferome try may be employed successfully. The discussion and the results are h elt general for making it possible to decide whether or not to apply t his method for an actual problem. An example (an object being longitud inally homogeneous with respect to the direction of light: end-on obse rvation) shows how to use the presented results for calculating the de tection limits of the method for a given object geometry.
