摘　　要：从理论上分析了载有物像信息的子弹光在烟雾介质中传播时强度的变化及极限传输距离，提出了一种基于光偏振特性验证该理论的新实验方法，其实验结果与理论分析一致，并讨论了利用该实验装置在实际雾中成像场合下改善信噪比。In this paper, the transmission situation of a ballistic light carrying the information of the object image in fog is analyzed. Its intensity reduction and traveling distance limitation are discussed. This new kind of experimental method based by the characteristic of a polarized light is presented. The experimental result which is in good agreement with theory is given. The probabilities of increasing signal to noise ratio and enhancing the quality of an imaging in fog with this experimental method are discussed.
