| Abstract: | In this paper,We study the properties of speckle fields emitted by the sin-
gle multimode optical fiber and multimode fiber-optic boundle under illumination
of the He-Ne laser light.The difference among the speckle-fields emitled 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 cxperimcnts,and the field can be used in optical
measurement and information processing. |
