本文研究了He-Ne激光照明多模光纤束产生的斑纹场特性，讨论了不同芯径光纤组成的多模光纤束产生的斑纹场之间的差别，并与毛玻璃斑纹场进行了比较，表明多模光纤束辐射的斑纹场可用于光学测量和信息处理。

In this paper, we study the properties of speckle fields emitted multimode fiber-optic boundle under illumination of the He-Ne laser light. The difference among the speckle-fields emitted by the multimode fiber-optic boundles, which consist of fibers of different cope diameters, is discussed, and compared with the speckle-field of frosted glass. The rightness of conclusions has been verified by the experiments, and the field can be used in optical measurement and information processing.
