实验确定了两个熔融石英柱体在垂直入射(波长441.6 nm)下的整个光散射矩阵。通过与Mie理论的比较，确定了0.960+/-0.002和3.091+/-0.003微米的半径，表明用偏振光散射技术可以测量微米级的光纤半径到几个纳米以内。单根光纤为偏振浊度计提供了一个很好的校准源，没有溶液中球体固有的问题。纤维是一种众所周知的几何形状，容易受到不规则形状的扰动，因此它为研究不规则粒子的散射提供了起点。
The entire light scattering matrix is experimentally determined for two fused silica cylinders illuminated at normal incidence (lambda441.6 nm). Radii of 0.960 +/- 0.002 and 3.091 +/- 0.003 microm are determined by comparison with Mie theory indicating that micron-sized fiber radii can be determined to within a few nanometers by polarized light scattering techniques. The single fiber provides a good calibration source for polarization nephalometers, being free from problems inherent with spheres in solution. The fiber is a well-known geometry which is amenable to perturbation toward irregular shapes, and as such it provides the starting point for studying scattering from irregular particles.
