摘要
探究在浑浊介质中利用物体的米勒矩阵进行目标识别的技术。米勒矩阵的16个矩阵元可以完整地描述物体的偏振信息,基于各物体不同的偏振特性,不同物体有不同的米勒矩阵。可以以物体退偏特性因子Δ或其中一米勒矩阵元作为灰度值得到一幅图像,利用图像的均值、标准差、信息熵和方差对图像进行评价。实验结果表明这种方法能够较大地提高成像质量。
The technique of target identification in the opacitas medium by using the Mueller matrix of the object was researched.Based on the different object has the different Mueller matrix and different polarization characteristics,the Mueller matrix＇s 16 matrix elements could describe polarization information of the object completely.The depolarization factor or a Mueller matrix element of the object is worth as the gray scale to a new image,and the image average value,the standard deviation,the information entropy and the variance of the image was evaluated.The experimental result indicated that this method can improve the image formation quality greatly.
