The degree of coherence function of a light beam could be used for optical encryption, robust optical imaging, and other purposes. However, recent works demonstrated that it has a puny self-reconstruction ability that gets worse as the obstacle is further away from the source. In this manuscript, we propose a method by which, with the help of only the introduction of a cross-phase structure in the degree of coherence function, the self-reconstruction ability of the degree of coherence function could be significantly enhanced. The performance of the method is independent of the location of the obstacle. The results, achieved in this manuscript, will shed new light on optical imaging, optical encryption, and optical communication in a complex environment.

通过操纵交叉相位结构增强光束相干度的自重构能力

光束的相干函数程度可用于光学加密、稳健的光学成像和其他目的。然而，最近的工作表明，它具有微不足道的自我重建能力，随着障碍离源头越远，这种能力就会变得越差。在这份手稿中，我们提出了一种方法，通过该方法，仅在相干度函数中引入交叉相结构，就可以显着增强相干度函数的自重建能力。该方法的性能与障碍物的位置无关。在这份手稿中取得的结果将为复杂环境中的光学成像、光学加密和光通信提供新的思路。
