| 英文摘要 | Based on the principle of Shack-Hartmann wavefront sensors (SHWFS), the differential angle-of-arrival fluctuation coefficient, the slope structure-correlation coefficient, the generalized slope correlation coefficient, the variance of the angle-of-arrival fluctuation, the slope structure function, and the slope structure-correlation function are used to evaluate the power law exponent beta of the phase power spectrum and the generalized atmospheric coherence length rho(0) for non-Kolmogorov turbulence. These methods used to evaluate the atmospheric parameters are compared by introducing the additive measurement noise of SHWFS. The differential angle-of-arrival fluctuation coefficient, the slope structure-correlation coefficient, and the generalized slope correlation coefficient are only related to beta and independent of rho(0). The slope structure-correlation coefficient and the slope structure-correlation function can remove the effect of the measurement noise. The SHWFS data in the atmospheric experiments for laser beam propagation through a 1000-m horizontal path are utilized to evaluate beta and rho(0) according to the methods.
