“…One of the most effective approaches to computer correction is based on the solution of the inverse problem of retrieval of the structure of an object from its blurred image [1,2]. For the correct solution of the inverse problem (deconvolution) under conditions of strong turbulence, the accumulation of images is commonly used [2][3][4][5]. A disadvantage of this approach to the formation of isoplanar distorted images is impossibility of analyzing dynamically changing scenes of observation.…”

The effectiveness of the reconstruction of images formed by single- and multi-aperture systems and distorted by an atmospheric turbulence is analyzed in this work. Based on numerical simulation, we show that the use of multi-aperture observation systems for the computer correction of atmospheric distortions under anisoplanar conditions can significantly reduce the exposure time. Main distortions are well corrected during image synthesis for a short exposure time, which corresponds to a “frozen” turbulence. The time required for the correction of residual small-scale distortions is an order of magnitude shorter than in the case of synthesis of long-exposure images with the use of traditional single-aperture observation systems.

In this paper, we consider the influence of various factors and interference invariant transformations measuring information on autoreflection schemes alignment control. Theoretical and experimental studies of an error for biprizm scheme. Shown that the main influencing factors are non-linear transformations in optical systems and the impact of the air path. Experimental studies were conducted based on two alignment control opto-electronic systems in which the control element (CE) is configured as one or two corner-cube retroreflectors.
