Abstract

We are presenting the results of the studies related to propagation of ultrashort optical pulse through the turbulent atmosphere. The correlation of the atmospheric turbulence with the propagation delay fluctuation was measured. The entirely different approach in comparison to adaptive optics was developed to describe the effect. The experiments described enabled us for the first time to determine the L₀ parameter on the basis of direct measurement. The recent achievements in the field of pulsed lasers, fast optical detectors and timing systems enable us to resolve the effects of propagation differences monitoring on the level of units of picosecond propagation time. Three independent types of path configurations have been studied: horizontal path, slant path at elevation 10 - 80 degrees to a flying target and slant path from ground to space. Additionally, new techniques of optical receivers signal processing give a way to distinguish the atmospheric fluctuations contribution from the energy dependent detection delay effects.
