Original Abstract

The resistance of signal transmission to atmospheric phenomena is possible to solve partially by means of the special optical intensity distribution at the beam spot (i.e. by means of the special beam profile). In practice the resultant beam profile can take users of the free space optical link by surprise if only computer models of the optical beams are used and any diffraction effect at the transmitting lens is not considered. Two models of diffraction of optical beam radiated from the optical transmitter are presented and two methods of the beam modeling are clarified (the method based on the Bessel function integrating and the method based on FFT). Confirmation of the models elaborated is a part of the contribution.
