相位互异散斑校正技术研究

相位互异散斑（PDS）是一种新颖的成像技术，可用来克服由于未知相差（如大气扰动）带来的图像退化。利用泽尼克多项式拟合未知扰动造成的相位失真，并用一对图像求得波前相位。从分析相位互异散斑技术的机理出发，使用遗传算法作为迭代算法，基于仿真实验数据验证了该技术的可行性，并在仿真实验中分析影响该技术性能的一些因素，如泽尼克多项式模式和湍流大小的影响等。这些研究结果为探索模糊图像恢复提供了新的途径。

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.
