Estimation of the Turbulence and Regular Refraction Effects on Laser Beam Parameters in the Atmospheric Boundary Layer: Part 1, Coherence Length and Turbulent Broadening

Efficiency of stabilization of laser radiation on the stand of an adaptive optical system

“…The error of the adaptive system on the bench has an irregular or random character and is determined by a value that depends on the intensity of turbulence on the path [25].…”

Determination of the Structural Characteristic of the Refractive Index of Optical Waves in the Atmospheric Boundary Layer with Remote Acoustic Sounding Facilities

“…As a result, using the experimental dataset (under convection conditions) and assuming H = d 75 m, we obtained the set of calibration coefficients B r (f), remembering that that the coefficients B r (f) are unique for every sodar antenna and every acoustic frequency used for the sounding. We also used this approach to determine B r (f) in our earlier words [24,25]. The results obtained imply the necessity of periodic refinement of the calibration coefficients for all sodar measuring channels and all frequencies used.…”

“…However, most existing techniques for interpreting the results of acoustic sounding of the atmosphere employ equations similar to Equation (1) (see References [9,21,23]). We also used Equation (1) as a basis, and wrote the equation for calculation of C 2 T (H) as follows [24][25][26]:…”

“…This allows the calibration coefficient B r (f) to be determined (calculated). The results reported below were obtained by applying the second approach, using measurements of the turbulence in the surface layer recorded by ultrasonic anemometers-thermometers [24,25]. This technique was also used, for example, in References [21,22].…”
