Modelování vlivů turbulentního proudění na optický svazek v prostoru

Abstract

This thesis is about issues of atmospheric turbulence on diffusion of the optical beam in the free space. Therefore it was needed to learn the issues of turbulence flowing in atmosphere. After that numerical models of the turbulence simulations were made in ANSYS Fluent 15 on the basis of real measurement. Simulations of mechanical and thermal turbulence were made in laboratory box. After that each model were compared with real measured values. The last part of the thesis is about how turbulent influence Gaussian beam. Influence of mechanical and thermal turbulence was measured. In the last part of the thesis were simulated transition of the beam through plexiglass and glass. The next models were about transition Gaussian beam through two plexiglass which simulate laboratory box.
