OPTICAL METHOD FOR ANALYSIS OF ATMOSPHERIC EFFECTS ON LASER BEAMS

Abstract

The report describes the design of an instrumentation system for the study of the effects of atmospheric turbulence on a collimated laser beam under near-earth conditions. The instrumentation consists of a helium-neon laser with optical collimator and a receiving system of 24-inch aperture with narrow bandpass filter. The Appendix presents examples of beam cross section patterns for different propagation conditions. The method of analyzing spatial intensity distributions of these patterns is described.
