【摘要】 在物质的三个基本光学参数折射率、光吸收系数和光散射系数之中,散射系数最复杂,一方面源于散射规律的复杂多变,另一方面源于散射系数的多方向性;后者使散射系数在不同应用场合可能具有不同的含义。然而,很多人对此缺乏正确认识,错用散射系数及其散射规律。文章从介绍散射系数的方向性入手,对几种常见的不同含义的散射系数进行释义,包括拓展的Lambert定律、Kubelka-Munk理论、瑞利散射定律以及Mie散射定律等规律中的散射系数,建议在不同散射系数前加限定词以利区分,并提出建议用词,同时说明其适用场合。更多还原

【Abstract】 Scattering coefficient is more complicated than refractive index and absorptioncoefficient due to its multi-direction and the complicated scattering laws. Themulti-direction of it makes different scattering coefficients in different situation, such as inLambert law, Kubelka-Munk theory, Rayleigh scattering theory, Mie scattering theory, andso on. Some non-optics researchers don’t recognize these and misuse them. This papergives detailed explanations of the meanings of scattering coefficients mentioned above byintroducing the directions of them. Meanwhile, more appropriate names for them aresuggested to be used in order that they are more easily understood by any user. At last,examples are given on in what situation which scattering coefficient should be chose to use.更多还原
