| 摘 要： | 提出基于红外光的偏振度来确定透明物体形状检测中的入射角的方法。在可见光域,偏振度是入射角的二阶函数,即在布儒斯特角两侧各有一个入射角,不能唯一确定入射角。而在红外域,偏振度与入射角之间是一一对应关系,可以对可见光域的两个入射角做出区分,得到正确的入射角。这种方法提高了透明物体形状检测的精度,还可用于复杂形状的物体检测。

| Abstract: | A new method to determine the incident angle in the shape detection of transparent objects was given in this paper. This method was based on the polarization degree of infrared light .In the visible domain,the polarization degree is a secondorder function of incident angle.There was an angle on each side of the Brewster's angle,so the incident angle can not be uniquely determined. In the infrared light domain,the polarization degree and the incidence angle are in the one-one correspondence.You can make a di... |
