摘要
介绍了多模光纤在动态光散射中的应用,搭建了基于多模光纤的动态光散射实验系统,并用该系统测量了单分散、多分散以及不同浓度的标准聚苯乙烯乳胶球悬浮液.结果表明,该系统可准确地测量浓度达4.5%的聚苯乙烯乳胶球溶液中悬浮颗粒的粒径分布.
The application of multimode fiber in dynamic light scattering （DLS） experiment is introduced. DLS experiment system based multimode fibers is described. Mono-dispersed, poly-dispersed suspensions of standard polystyrene latex particles are measured using this system. The results show that even for the suspensions containing up to 4. 5% volumes of 200 nm polystyrene latex spheres, the size distribution of the particles can be measured precisely.
