随着成像技术的发展，偏振信息在成像技术中的应用逐渐受到广泛的重视。偏振信息的提取方式就显得尤为重要。穆勒矩阵作为表示光照射到物体前后偏振态变化的系数矩阵，其不仅与物质本身息息相关，而且含有大量的偏振信息。此外由于穆勒矩阵含有16 个元素，且每一个元素含有的信息都不尽相同，充分利用这些信息能够在目标识别、目标信息增强方面以及目标与背景分离的应用中起较好的促进作用。通过提出一种穆勒矩阵图像的获取方式，并对穆勒矩阵的信息加以初步的处理，最后与偏振度的信息加以对比，充分体现出穆勒矩阵图像在偏振成像应用中所具有的价值。结论表明通过穆勒矩阵图像处理后得到的图像比偏振度图像信息更加完整，能够对后期的模式识别处理提供良好的基础。

As the development of imaging technology, application of polarization information in this field has a wide鄄ranging appreciation gradually. Therefore, the way of extracting polarization information is particularly important. Mueller matrix, the coefficient matrix which shows the change of polarization state before and after light shining on object, not only has a closely relation to the material itself, but also contains quantities of polarization information. What忆s more, Mueller matrix has 16 elements each containing different information. Consequently, an adequate used on these information plays a catalytic role in target identification, information enhancement, as well as separation of target and background. Through presenting a method to acquire Mueller matrix image, a comparison was made with Dop(degree of polarization) information and at last the result indicated the value of Mueller matrix image in application of polarization imaging. The conclusion suggest that, compared with Dop image, the image processed by Mueller matrix has more integrity information, so as to provide a preferable foundation for pattern recognition later.
