Using high-speed,multi-cell Shack-Hartman wave-front sensor,the measurement of temporal and spatial feature to a rolling phase screen laboratory atmospheric turbulence generator is presented.In terms of spatial feature,coherence length of the atmospheric turbulence and phase spatial structure function of the wave-front are calculated,and the variance distribution of the wave-front Zernike coefficient is compared to the theory as well.In addition,on the temporal feature,the Greenwood frequency and time power spectrum of the simulated turbulence are analyzed.A new method that is called residual variance algorithm to calculate the time constant is proposed.The result shows that the atmospheric turbulence generated by the rolling phase screen is consistent with the Kolmogorov turbulence.
