The analytical theory of multiple scattering [J. Opt. Soc. Am. 60, 1084 (1970)] permits predictions of scattering patterns by homogeneous suspensions of aligned and randomly oriented particles. Predictions for randomly oriented particles have been tested previously. Using an optical system involving a He-Ne laser and suspensions of red blood cells, we tested the theory's predictions for scattering by suspensions in two distinct alignments. The qualitative effects of cell alignment on light scattering are consistent with those predicted, although measured differences in scattering between the two alignments exceed those predicted. We conclude that the theory may provide an optical means of distinguishing particle orientation in multiple scattering suspensions.
多重散射的分析理论[《美国光学学会杂志》60, 1084 (1970)]可以预测由排列整齐和随机取向的粒子组成的均匀悬浮液的散射模式。之前已经对随机取向粒子的预测进行了测试。我们使用一个涉及氦氖激光器和红细胞悬浮液的光学系统，测试了该理论对两种不同排列的悬浮液散射的预测。细胞排列对光散射的定性影响与预测结果一致，尽管两种排列之间测量到的散射差异超过了预测值。我们得出结论，该理论可能提供一种光学方法来区分多重散射悬浮液中粒子的取向。
