此外,Henyey-Greenstein相函数还可以用来模拟太阳光照射地表时的反射和折射现象,以及在太空中的星光的散射现象。 总之,Henyey-Greenstein相函数是一种用于描述光线散射的函数,它可以用来模拟多种物理现象,如太阳光的散射、空气中的气溶胶的散射、雾的散射等。它的应用非常广泛,可以用来模拟太阳光照射地表时的反射和折射...
打开非序列元件编辑器中矩形体(本例中为物体2)的物体属性 (Object Properties),在体散射 (Volume Physics)选项卡中可以看到,该散射模型为DLL文件散射 (DLL Defined Scattering)并且DLL文件选择“Henyey-Greenstein-bulk.DLL”: 系统中使用的DLL文件及源代码(.c文件)默认位于Zemax根目录下DLL > BulkScatter文件夹中。
我们首先讨论对Rayleigh相函数进行统计抽样方法研究,用取舍抽样、直接抽样和制表法三种方法对Rayleigh相函数进行采样,并将三种抽样方法应用到Henyey-Greenstein(HG)相函数中。并且为了模拟不同介质中的散射特征,将HG相函数作相应的改进得到RayleighHenyey-Greenstein(RHG)相函数和ModifiedHenyey-Greenstein(MHG)相函数,并使用...
The Henyey-Greenstein model describes the angular distribution of light scattered by small particles. This model has been applied to numerous situations, ranging from the scattering of light by biological tissue to scattering by interstellar dust clouds. Let's learn how to use a user-defined object...
Henyey-GreensteinWe study the relaxation of Li+ ions dilutely dispersed in He at equilibrium. We employ the Henyey-Greenstein phase function to model the angular dependence of the differential scattering cross section for Li+-He collisions. We solve the spatially homogeneous linear Boltzmann equation...

The Henyey-Greenstein model describes the angular distribution of light scattered by small particles. In this model, the angular distribution of scattered light is given by: The parametergcharacterizes the distribution. Forg= 0, the model describes a material with a uniform probability of ...
Approximate phase functions such as Henyey-Greenstein, modified Henyey-Greenstein, or Legendre polynomial decomposition are often used to simulate the Mie phase function. An alternative solution using an exact calculation alleviates these approximations. DOI: 10.1364/AO.35.003270 年份: 1996 ...
