Paper Abstract

We have constructed wavefront compensated system that measures wavefront tilt of laser through the generated turbulence of the convective tank in laboratory. The wavefront tilt power spectral density has been measured. The measurements of optics characteristic in tank have been also measured simultaneously. The spectra show distinct asymptotic slopes, in general, agree with theoretical pre- dictions based on the Kolmogorov model. This paper reports on the results of some experiments made to evaluate the performance of the system, and to improve characteristics of turbulence in the con- vective tank. Spectral analyses of these signals allow to study bandwidth of this system. We study the behaviour of image distortion in order that the compensation system can be established.
