Abstract

Statistical parameters of laser beams counter propagating in the atmosphere are analyzed on the basis of numerical simulation, as well as a possibility of implementing the reciprocity principle of the counter propagation of optical waves from point sources with the aim of cryptographic keying with the help of finite-size receiving-transmitting apertures. The dependences of the degree of correlation of signals from coupled wireless optical communication laser systems on the distance and aperture sizes are studied. The quantitative dependence of the aperture size on the space between the laser systems is derived with the aim of maintaining the correlation degree at a level above 0.9999.
