Technique of phase diverse speckle correction

Phase diverse speckle (PDS) is a novel imaging technique, which can be used to overcome the image degradation caused by unknown phase aberrations, such as atmospheric turbulence. The phase distortion generated by the unknown turbulence was fitted with Zernike polynomials. The wave-front phase was derived from a pair of images. Based on the mechanism analysis of the PDS technology and taking the genetic algorithm as the iterative algorithm, the feasibility of this technology was verified by the simulation data, and some factors including the Zernike polynomials′ mode and turbulence which influences the qualification of this technology were analyzed during the simulation. The efforts provide a new way for the recovery of blurred images.
