通常的光电检测系统是根据光的强度差别来区分目标的,但当强度差别不明显时或目标所处的背景很杂乱时,用强度来区分目标是非常困难的.在文中,提出利用光的另一个基本特征-偏振特性来区分场景中的目标,可以克服由于强度差过小带来的目标检测上的困难.经过实验表明,利用光学偏振特征的成像传感器所获得的图像使得目标检测大大简化.

It is usual methods to use the intensity to detect the object in the optical-electricity system. But it is difficult to distinguish the object when object in clutter as the difference of the intensity between object and environment is not obvious. In this paper, the polarized characteristics of the light is used to distinguish the object in clutter. The difficulty brought by intensity can be overcome. It can be shown that this method can improve the efficient of the recognition.
