Environmental Effects on Light Propagation and Adaptive Systems IV.
As known, lasers are used for atmospheric communication. There are advantages of an optical wave system over a radio frequency system. But there arise a number of problems in that case. Turbulent fluctuations of density in the atmosphere cause variou

Turbulent fluctuations of density and pressure in air and argon in a shock tube have been investigated, as well as their interaction with a shock wave reflected from a perforated plate at the end of the shock tube. The Mach number of the incident sho

An image in one color is a scalar field. The image is associated with its vector gradient field. The analysis of vector fields with the help of single-length vector templates made it possible to indicate in the image such objects as vortices, Road Si

Conditionality is the main setting of Apparatus Function (AF) O to increase resolution. The conditionality is numerically equal to the reciprocal of the minimum value of Modulation Transfer Function (MTF) |M(O)| or the magnitude of this gap. We intro

Classification of varieties of super-resolution methods is based on the gap between the minimum value of the Modulation Transfer Function (MTF) M (O) (for discrete Apparatus Functions (AF) O) and zero. Classifiers underlie the concept of super-resolu

The problem of Super-Resolution begins with evaluating the working discrete model of the Apparatus Function (AF) of the device or the Antenna Pattern (AP) of the telescope. With the evaluation of such AFs, APs, we associate the mathematical problem o

When modeling physical processes, phenomena in radio-physics, optics, we propose to use Finite-Dimensional Sampling Theories (FDST) instead of the Wiener-Kotelnikov theorem and methods based on difference schemes, integral sums. Accurate FDST operati
