摘　　要：在自然光照条件下,用CCD相机获取树叶表面反射光的偏振信息,经过分析和计算,得到反映树叶表面信息的偏振度图像偏振度图像。在实验室条件下,对不同种类的树叶以及不同颜色的同种树叶样品进行了研究,结果表明PDI探测相对于传统的光度探测有一定的优越性,可以在军事目标识别和遥感探测领域发挥重要作用。The polarization information of light reflected from leaves＇ surface was obtained by CCD in natural lighting condition. With analysis and computing, the polarization degree images（PDl） which represent leaves＇surface information was gained. Different leaves and homogeneous leaves with different colors were researched in laboratory. The conclusion indicates that polarization degree image detecting is superior to conventional photometric detecting sometimes and can play an important role in military target identification and remote sensing detecting areas.
