水雾对红外光谱遮蔽衰减特性研究

从理论上简要阐述了水雾对红外光谱的遮蔽衰减特性，用朗伯—比尔定律描述、分析了红外光谱在辐射传输过程中辐射经水雾吸收和散射后的能量变化.同时用米氏散射理论解释、计算水雾粒子的散射系数、消光系数并考虑路径辐射过程其他因素的影响.并且通过检测评估说明了水雾对红外辐射能量的遮蔽衰减特性.

Research on Shading Attenuation Characteristics of IR Spectrum by Water Fog

The shading attenuation characteristics of IR spectrum by water fog are introduced briefly in theory. After the radiation absorption and scatter, its energy change is described and analyzed by Lambert Beer law during the transmission. The scattering coefficient of the water fog particle is described and counted simultaneously by the Mie Scattering theory and the effect of other factor is calculated during the path radiation. At last, the shading attenuation characteristics of IR radiation energy by the water fog are explained by verification and evaluation.
