Paper Abstract

Phase diverse speckle (PDS) is a novel imaging technique, can be used to overcome image degradation arising from unknown phase aberrations, such as atmospheric turbulence. The wave-front phase expanded on the Zernike polynomials is estimated from a pair of images (in focus and out of focus). This paper analyses the principle of PDS, uses genetic algorithm as the iterative algorithm, verifies its validation with numerical and experimental data, and studies some characteristics in simulation, such as the influence of Zernike polynomials' mode, defocusing amount and amplitude of turbulence on the phase estimation.
