Abstract
The mean intensity and the deviation from the straight-line propagation of the optical beam passed through the shock wave at the start of the path and then propagating in a homogeneous medium have been calculated. It has been shown that the spatial inhomogeneity of the refractive index of air in the region of the shock wave arising when a supersonic flow flows around a conical body can exert the focusing action on the beam passing through it. The angular deviation of the optical beam from the straight-line propagation owing to the shock wave depends only on the height above the Earth’s surface, at which the shock wave is generated. As the height increases, the influence of the shock wave on the optical beam propagating through it decreases.
