【摘要】 动态光散射技术是探测悬浮液中亚微米颗粒动力学性质的最有效方法。光纤的使用使得小型、便携及在线式动态光散射仪器成为可能。首先指出了多模光纤动态光散射系统的缺点,然后详细分析了各种单模光纤动态光散射系统的结构特点,最后指出了目前光纤式动态光散射研究的发展动向及其面临的问题。更多还原

【Abstract】 Dynamic light scattering has become the most effective method in probing the dynamic properties of sub-micron particles in fluid.Using of fibers has enabled portable,mini-sized and online instruments based on dynamic light scattering available.In this paper,the weakness of multi-mode fiber-optic dynamic light scattering systems has been indicated firstly.Then the structure and characteristics of various mono-mode fiberoptic dynamic light scattering systems have been analyzed in detail.The developped direction and problems will concern when studing fiber-optic dynamic light scattering have been listted finally.更多还原
