ESTIMATION SCINTILLATION INDEX ON A SUPERCONDUCTOR RECEIVER FOR GAUSSIAN LASER BEAM PROPAGATED TROUGH RANDOM PHASE SCREEN

Abstract

The goal of the present work is to study the regulations of the changes of the characteristics of high frequency optical signals using both quantitative and qualitative terms, on the basis of changes statistical parameters of turbulent media on the random phase screen model. There is an analytical assessment of statistical moments of laser radiation via random phase screen by numerical modelling and comparison with known experimental results. The object of the study is a random inhomogeneous atmosphere with weak turbulence, as well as optically dense turbulent media. The model of a random phase screen is discussed and the distribution of the statistical moments of scattered laser radiation is studied. The dependence of the effective size of the laser beam and the scintillation index on the correlation radius of the phase
screen in the plane of the detector for a random phase screen is estimated.
