Měření a modelování vlivu atmosférického prostředí na optický svazek v laboratorních podmínkách

Abstract

The thesis deals with the description of the theory of optical beam propagation, the influence of the atmosphere on the fiberless optical coupling and the characteristics of turbulent models. The second part deals with the effect of fog on the fiberless optical coupling in laboratory conditions for 5 wavelengths, using the received optical power through in a confined space. The aim of the work is to compare the induced beam scattering for the different wavelengths used. The third part consists in constructing a numerical model from the taken values. Using ANSYS Fluent, we simulate the properties of an aerosol, fog in a laboratory box using a proper turbulent model. The simulated aerosol frequency is compared with real measurements.
