Propagation of light through a random scattering media is a challenging, yet a highly practical problem in numerous fields, such as in astronomy, medical diagnosis, non-line-of-sight imaging, imaging through fog, etc. Scattering media distort the light and generate a random pattern without any directly useful information. Nevertheless, the randomness of the light plays a significant role in designing and developing correlation-based imaging and measurement techniques. Correlation optics exploits the intrinsic fundamental features of randomness to unveil hidden information within the scattered light. This mini-review highlights the role of polarization correlation and pilot-assisted beam guiding through scattering medium in information recovery through random scattering media. Here, one of the orthogonal polarization components of the light is loaded with the information and the other is without the information, and this special scheme of the colinear beam propagation through the random scattering medium is referred to as the pilot-assisted beam guiding. Such a pilot-assisted propagation strategy helps to counter the randomness and preserves the desired information through the scattering channel. In this article, we mainly focus on the recent progress and advancement in polarization correlation with pilot-assisted beam guiding in looking through random scattering media.

光通过随机散射介质的传播是一个具有挑战性的问题，但在许多领域中都是一个非常实际的问题，例如天文学、医学诊断、非视距成像、雾成像等。散射介质会扭曲光并影响光的传播。生成一个随机模式，没有任何直接有用的信息。然而，光的随机性在设计和开发基于相关的成像和测量技术中起着重要作用。相关光学利用随机性的内在基本特征来揭示散射光中隐藏的信息。这篇小型评论强调了偏振相关和通过散射介质的导频辅助光束引导在通过随机散射介质的信息恢复中的作用。这里，光的正交偏振分量之一加载有信息，而另一个则没有信息，这种共线光束通过随机散射介质传播的特殊方案被称为导频辅助光束引导。这种导频辅助传播策略有助于对抗随机性并通过散射通道保留所需的信息。在本文中，我们主要关注在随机散射介质中使用导频辅助光束引导的偏振相关性的最新进展和进展。
