Abstract

Two He—Ne lasers operating at 6328 Å have been utilized to make simultaneous measurements of the effects of scintillation over homogeneous optical paths of 650 and 1300 m to study the transfer of laser radiation through a turbulent medium. At the path terminus, multiple sampling of each laser beam was effected by use of a photo-optical technique that records a 61-cm cross section of an optical beam. Concurrent with the optical data, wind-speed and direction recordings were made at multiple points along the optical path in order to estimate the homogeneity of meteorological conditions. Near the path terminus, measurements of wind shear and temperature lapse were taken. In addition, high-speed-thermometry techniques were utilized to compute one-dimensional temperature spectra as well as the thermal structure coefficient CT. Data were gathered during temperature-lapse, neutral, and inversion conditions. Log-irradiance scans derived from the optical data were used to compute log-irradiance power spectra, variance, and other statistical quantities. From these optical and meteorological data, optical-filter functions were calculated for spatial frequencies above 87 cycles/m and are usedfor comparison with current theories. The saturation of the log-irradiance data is again observed, and the isotropy of the irradiance fluctuations is examined.

Here the authors consider only the perturbation in the phase structure function and, hence, the angle-of-arrival fluctuations. However, the beam profile is formulated in terms of a gaussian amplitude rather than a gaussian irradiance and is therefore not a solution for the TEM00 mode beam.
