Abstract

We have constructed wavefront compensated system that measures wavefront tilt of light propagation through the laboratory-generated turbulence in a convective tank. The measurements of optical characteristic in simulation cell have been measured. The wavefront tilt power spectral density and arrival-angle of fluctuations are also shown simultaneously The spectra show distinct asymptotic slopes, in general, agree with theoretical predictions based on the Kolmogorov model. The distribution variance of arrival-angle fluctuations follows (Chi) ² distribution.
