一种快速响应光传感器的设计

Development of a new type sensor for detecting laser with high speed

分析了激光入射晶体后激发的电极化强度特性,发现在与激光传输垂直方向存在一恒定电极化强度分量.基于此原理,设计了一种快速响应的激光探测传感器.

On the basic electromagnetic dynamics theory, the characteristics of electric polarization caused by laser in crystal are investigated in details, and a constant electric polarization in vertical direction to laser propagating is discovered. According to that, a new type sensor for detecting laser is designed, which has some characteristics such as high speed and simplicity. 
