抽象。提出了一种改进的散射介质散斑相关成像迭代算法。我们采用从双谱分析方法获得的近似解作为迭代过程的初始条件。与传统的双谱分析方法相比，该方法避免了传统迭代算法中在不同随机初始条件下多次运行的问题，减少了计算时间。因此，我们获得了图像质量和重建速度之间的平衡。实验结果证明了该方法的可行性。
Abstract. We present an improved iteration algorithm for speckle-correlation imaging through scattering media. We employ an approximate solution obtained from a bispectrum-analysis method as the initial condition of the iterative process. This method avoids several different runs performed with different random initial conditions in the traditional iteration algorithm and reduces the execution time in comparison with the conventional bispectrum-analysis method. Therefore, we obtain a balance between image quality and reconstruction speed. The feasibility of the proposed method is proved by the experimental results.
