利用新近研制的反射计对牛奶的光学性质进行了研究。这项研究的目的是，第一，测试的反射计的适用性，在估计的真实的折射率和散射在混浊的液体，第二，调查的光谱特性的一个特定的混浊的液体，即牛奶。牛奶的反射率的表达式被构造，其中考虑到牛奶中发生的光散射。与应用程序的最小化程序的反射率数据，它是可能的，同时获得牛奶的真实的折射率和散射参数。观察到的散射参数是线性依赖于牛奶脂肪浓度。
Optical properties of milk were studied with the use of a recently developed reflectometer. The purpose of the study was, first, to test the applicability of the reflectometer in the estimation of real refractive index and scattering in turbid liquids and, second, to investigate the spectral properties of one particular turbid liquid, namely, milk. An expression for the reflectance of milk was constructed which takes into account the light scattering occurring in milk. With the application of a minimizing procedure to the reflectance data, it was possible to simultaneously obtain both the real refractive index and a scattering parameter for milk. The scattering parameter was observed to be linearly dependent on the milk fat concentration.
