Anisoplanatic turbulence correction in incoherent imaging by using reference sources with different wavelengths

Abstract

The possibility of the phase compensation of turbulent distortions of incoherent images of an object illuminated by radiation with different wavelengths is investigated. The research is carried out based on the method that is a further improvement of the algorithm for the numerical simulation of incoherent imaging through the atmosphere in conditions of anisoplanatic turbulence developed by the authors [Lachinova S.L., Vorontsov M.A., Dudorov V.V., Kolosov V.V., Valley M.T. // Proc. SPIE. 2007. V. 6708. 67080E]. The dependence of the degree and region of the enhancement of the image on the ratio of the reference wavelength to the image-forming radiation one is shown.
