MULTIWAVELENGTH LASER PROPAGATION STUDY.
Abstract
The major objective of this program is to experimentally investigate the wavelength-dependence of turbulence effects on optical propagation through the atmosphere, and to relate the results to certain meteorological parameters, theoretical models, and model-independent dimensional analyses. The experiments are conducted with the use of simultaneous, spatially-coincident laser beams at three wavelengths in the visible and infrared spectrum, with special covariance and large-aperture receivers and real-time processing for the various statistical results. An improved, nonoptical system for the determination of the turbulent structure is also utilized. In particular, it is important that the wavelength-dependence of the saturation of scintillations be understood, and that the range of validity of the generally accepted atmospheric model be further investigated.
