摘要

人体浅层组织经常发生病变，这些组织表面存在多种散射介质，如粘膜、脂肪和血液。在这种散射环境中，使用传统的基于衰减的成像方法很难分辨出病变的位置，而基于偏振的成像方法对此信息更为敏感。因此，本文使用稀释牛奶模拟具有散射效应的生物组织，在非偏振光源的照射下进行实验，并使用优化的鲁棒偏振去散射算法进行图像处理。实验结果通过局部强度比较和视觉保真度函数进行了定性和定量分析，验证了该算法在特定条件下的有效性。

Polarization-Based De-Scattering Imaging in Turbid Tissue-like Scattering Media

In shallow tissues of the human body, pathological changes often occur, and there are several kinds of scattering media, such as mucosa, fat, and blood, present on the surface of these tissues. In such scattering environments, it is difficult to distinguish the location of the lesions using traditional attenuation-based imaging methods, while polarization-based imaging methods are more sensitive to this information. Therefore, in this paper, we conducted experiments using diluted milk to simulate biological tissues with scattering effects, illuminated with non-polarized light sources, and used an optimized robust polarization de-scattering algorithm for image processing. The results were qualitatively and quantitatively analyzed through local intensity comparison and visual fidelity functions, verifying the effectiveness of this algorithm under specific conditions.

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
