光的偏振特性在汽车车灯视觉系统的应用 摘 要:在所有交通事故中,夜间行车发生的交通事故不在少数,其主要原因是对面行驶的汽车远光灯太亮导致司机产生炫目而视野模糊。本文旨在把偏振光的强度特性,应用到汽车车灯视觉系统中,并通过测量氦氖激光器透过偏振片后的光强变化来模拟偏振片对汽车车灯的影响的实验验证后,得出用偏振片制作汽车车灯和司机佩戴偏振片眼镜的方案比较合理。该方案可以解决会车时产生的炫目问题,从而提高夜间汽车行车的安全性。

Application of Polarization State of Light in Automobile Headlights Vision System
Abstract: In all traffic accidents, traffic accident driving at night a few, mainly because of cars across the drivers produce high beam is too bright dazzling and blurry vision. This article aims to apply the strength properties of polarized light to the car headlights in the visual system. After the experimental verification by measuring the light intensity change of the He-Ne laser through the polaroid to simulate the influence of polaroid on the car headlights. We can find that the car headlights made with polarizer and the driver wearing polarized glasses is more reasonable. The project will be can solve the problem arising from glare, thereby improving the safety of driving car at night.
