硫系玻璃在汽车夜视系统中的应用

Application of chalcogenide glass in car night-vision system

  • 摘要: 夜间行车时,由于光线不足,视距较短,驾驶员驾车的危险性增加。汽车夜视系统能增加驾驶员夜间行车的视距,且不受雨雪等恶劣条件的影响,因此,颇受关注。夜间行车时环境温度变化较大,温度变化严重影响夜视系统的成像质量,无热化设计是夜视系统的发展方向之一。硫系玻璃具有较小的折射率温度系数和良好的红外透过性能,同时具备模压成型等优点,是用于无热化汽车夜视系统设计的优良候选材料。详细分析了硫系玻璃的光热特性,比较了硫系玻璃应用于汽车夜视系统的优势,给出了它在夜视系统中的多个应用实例。

     

    Abstract: Because of the limits of illumination in the cars, the drivers can't observe clearly at night, which greatly increases the driving dangers. Car night vision system is a novel technology that helps to increase the driver's observation distance and is not subjected to the adverse conditions such as snow and rain. Novel car night vision system has has been widespread concerned. However, the change of temperature has a great impact on night vision system. Chalcogenide glass has a high-transmittance rate in infrared spectrum regions, and also has the advantages of small temperature coefficient of refractive index and modling which is suitable to car night vision systems. The features of chalcogenide glass were analyzed, the advantages of chalcogenide glass in night vision system were summarized. Car night vision systems using chalcogenide glass were presented.
