The aim of the paper is to present the method for the detection of the atmospheric turbulence influencing optical wireless links. The experimental measurements were provided by the Michelson interferometer. Interferential patterns with one and four interferential fringes were adjusted by the appropriate optical components. Infrared source generating the turbulence was placed into the measuring arm...
Free space optical (FSO) communication links offer a number of advantages over radio frequency links. Main advantages of FSO communication links are electromagnetic compatibility, license-free band and high data rate. However, reliability of these links is highly dependent on atmospheric and weather conditions. An optical wave propagating through the atmospheric transmission media is very sensitive...
The paper deals with study of temperature turbulences effect towards the optical beam. The horizontally and vertically polarized optical beams have been studied. The turbulence flux has the vertical direction and the optical beam is propagating through the atmosphere environment with three different states of turbulences. The evaluation of obtained data was done by means of relative variance of optical...
This paper deals with the influence of atmospheric turbulence on the rangefinder laser beam. Analogous to the optical wireless links, turbulent flow causes optical intensity variation at the receiver plane. In optical communication, most problems namely at longer distances, are caused by beam scintillation and by beam wandering. In range finding systems, a strong influence from irradiated surfaces...
This work is focused on the optical wireless links working in turbulent atmospheric transmission media. A phenomenon of atmospheric turbulence is briefly introduced and relative variance of optical intensity in laser beam profile is presented. The goal of this paper is to determine the distribution of optical intensity relative variance in laser beam profile. According to the experimental results...
