The field reflected of a telescope focal plane highlighted by a laser is calculated. The method of physical optics is used. The size of dispersion spot on the receiving aperture plane is determined on depending of parameters of a line and telescope, coordinates of the maximum reflected signal and level of signal in maximum. Correlation of received signal level and quantity of the information in it also are received. On the basis of analysis of these correlation the losses in the communication laser channel caused by not an optimality of laser and channel parameters are designed. It is offered to consider a complex parameters of system at which dispersion spot contains the given quantity of the information as criterion of orientation.
