Effect of Slewing on the Frequency Spectrum of a Laser Beam in a Turbulent Medium

Abstract

In this report, the author discusses the effect of slewing on the temporal frequency spectrum of the scintillations of a laser beam propagating through a turbulent medium. It is assumed that the turbulent medium is characterized by the index of refraction n(r,t) = 1 + (n sub 1)(r,t), where the fluctuation (n sub 1) is much < 1. It is further assumed that (n sub 1) varies sufficiently slowing in comparison with the time required for the signal transversal.
