Paper Abstract

For non-Kolmogorov turbulence, the slope structure function and the slope correlation function are used to characterize atmospheric turbulence parameters--(beta) , which is the power-law exponent of the phase power spectrum, and (rho) 0, which shows the strength of atmospheric turbulence. The slope structure-correlation function, which is related to (rho) 0 and (beta) , and the slope structure-correlation coefficient, which is only the function of (beta) and independent of (rho) 0, are developed considering the subaperture size and additive noise. The Shack-Hartmann wavefront sensor data in the recently completed horizontal atmospheric experiments for 1000 m laser beam propagation are utilized to evaluate (beta) and (rho) 0 according to the developed theory.
