DETERMINATION OF THE RAY PHASE FOR PLASMA CYLINDER USING MODULUS OF THE PROBING RADIATION TRANSMITTIVITY
V.G. Zatsepin et A.V. GolubevInstitute for Physical Problems, Moscow U.S.S.R.
Abstract
Method for determination of the phase shift along the ray trajectories in side-on probing of plasma cylinder is presented. The unknown phase function Φ(y) is restored by calculation of the first derivative Φ'(y) which is proportional to the probing beam deflection angle and defines the refractive decrease of plasma transmittivity. This method is usable under strong absorption and refraction conditions, as well as in the case when phase of the probing beam is substantially distorted.
