摘要

研究散斑旋转去相关的原理,分析散斑旋转去相关角的影响因素,推测出散斑旋转去相关角主要受散斑无序程度和计算时所用散斑面积大小这两方面因素的影响。为进行实验验证,分别改变光学系统的四个可调参数来观测散斑旋转去相关角的相应变化,即改变计算时所用的散斑面积、改变散射介质到探测器的距离、横向平移探测器、更换散射介质。实验结果表明,计算时选取的散斑面积越大、无序程度越高,对应的散斑旋转去相关角越小。在基于记忆效应的散斑成像中,研究结果能够给散斑旋转去相关的相关研究和应用带来帮助,具有一定的实际意义。

Abstract

In this paper, we analyze the principle of speckle-rotation decorrelation, including the factors that influence the speckle-rotation decorrelation angle. We infer that this angle is mainly affected by the degree of speckle disorder and the size of the speckle area used in the calculation. To perform experimental tests, we change four parameters of the optical system and observe the corresponding changes in the speckle-rotation decorrelation angle. Specifically, we change the speckle area used in the calculation, change the distance between the scattering medium and the detector, shift the detector horizontally, and replace the scattering medium. The experimental results show that the larger the speckle area and the higher the degree of disorder, the smaller is the speckle-rotation decorrelation angle. In speckle imaging based on the memory effect, these research results can help both related research and applications of speckle-rotation decorrelation that have practical significance.
