| 摘要: |
| 根据MIE散射理论，计算了雾霾天气下，可见和红外波长范围内的气溶胶的消光系数和成像系统的水平探测距离。结果表明在雾霾天气下，随着波长的增加，消光系数减小，水平探测距离也随之增加。并在雾霾天气下使用不同波长的可见和红外成像系统进行成像对比实验，验证了上述结论。证明了红外成像系统在雾霾天气下成像性能优于可见光成像系统，可用于解决雾霾天气下能见度急剧下降的问题。 |

| Abstract: |
| Base on Mie theory, reported the extinction coefficient of the aerosol and the detection range of image system during haze-fog episodes from visible to long wave infrared. The results show that during haze-fog episodes, the extinction coefficient will decrease and the detection range will increase , with the increase of wavelength. And a serial of image experiment with different wavelengths of visible and infrared image system have been performed to demonstrate the above conclusion. Shows that during haze-fog episodes the performance of infrared image system is better than that of visible image system, can solve the problem of visibility dropped sharply. |
