The paper is focused on the comparison of Top Hat and Gaussian beam properties from the perspective of received optical power. Gaussian beam is very well known, so there isn't necessary to describe it, on the other hand Top Hat beam, which is created from Gaussian beam, isn't used so widely. Creation of Top Hat is briefly described in this contribution. The main point of the contribution is comparison...
This work is focused on the quick determination of characteristics of the atmospheric transmission media in optical band. Optical wireless links are briefly introduced. Two of the most important effects influencing optical signal properties in the atmosphere are shortly described. The goal of the work is in analysis of optical intensity profile. Due to the changes in the intensity profile we are able...
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...
