Abstract:

The results of analysis of the mean intensity, intensity fluctuations, and regular and random wandering of the optical beams, crossing a shock wave, arising in the vicinity of a conical body moving with supersonic speeds in a turbulent atmosphere are present. It is shown that with increase of the optical turbulence strength the aero-optic effects, caused by the shock wave, are suppressed. Quantitative data, illustrating manifestation of the aero-optiŅ effects on paths of different geometry and length depending on the turbulent conditions of propagation of light, are presented and discussed in the paper.

Keywords:

shock wave, mean intensity, turbulence, variance of intensity fluctuations
