“…Here, as shown in Fig. 1 A unique property of the imaging through refractive turbulence is the so-called "third PSF constraint" [5], first described in [12], or orthogonality of Green's functions, [13]. It can be formally represented as…”

“…In [4] image fluctuations caused by translational shifts between image frames are used estimate the turbulent strength. Authors use the phase screen-based, and therefore isoplanatic [5], theory to support their technique, but in our opinion isoplanacity is not an essential constraint. Even the authors' naïve fluctuation model reflects the complex dependence of fluctuations on the local contrast: the large fluctuations areas associated are with the highcontrast areas of the scene.…”

“…Energy conservation is a fundamental property of the waves propagating through refractive random media [9]. It has profound implications on the imaging through turbulence [10], propagation of the conjugated waves [11], and the shape of the covariance function of irradiance [9]. Scintillation reduction for the partially coherent beams is intimately related to energy conservation.…”

“…Al capturar imágenes con luz incoherente que ha atravesado una atmósfera turbulenta, la intensidad de la imagen (en el plano del receptor) fluctuará más en los bordes de alto contraste [152] y apenas lo hará en las regiones uniformes; por lo tanto, la representación visual de σ 2 I i,j se verá como un filtro de borde aplicado a la imagen del objetivo. Para poder localizar y contar solamente los píxeles con un centelleo relativamente alto, se puede aplicar un valor umbral τ a la representación del índice de centelleo definiendo un conjunto…”
