散斑对APSCI方法和Mueller成像的影响
Effect of speckle on APSCI method and Mueller Imaging
摘要:
称为APSCI(自适应偏振状态对比度成像)的偏振成像方法的原理是使用特定的照明和检测偏振状态来最大化对象与其背景之间的偏振对比度。在这里,我们进行了比较研究的APSCI方法与现有的经典穆勒成像(CMI)与极性分解的存在下,完全和部分偏振的圆形高斯散斑。结果表明,显着增加的巴塔查里亚距离作为我们的对比度参数的APSCI方法,特别是当对象和背景同时表现出几个偏振特性。
英文摘要:
The principle of the polarimetric imaging method called APSCI (Adapted Polarization State Contrast Imaging) is to maximize the polarimetric contrast between an object and its background using specific polarization states of illumination and detection. We perform here a comparative study of the APSCI method with existing Classical Mueller Imaging(CMI) associated with polar decomposition in the presence of fully and partially polarized circular Gaussian speckle. The results show a noticeable increase of the Bhattacharyya distance used as our contrast parameter for the APSCI method, especially when the object and background exhibit several polarimetric properties simultaneously.
