摘要
介绍一种用多模光纤传输入射和反射激光的速度干涉仪，阐述了这种干涉仪的原理和结构，并将其与传统的速度干涉仪进行比较。给出了用这种干涉仪测量电爆管的弹丸速度和钨样品在铁飞片冲击压缩下的自由面速度的实验装置和结果。文中最后总结了这种干涉仪的性能及特点。
In this paper,a velocity interferometer which uses multi-model fibres totransmit incident and reflective laser is introduced.The principle and the structure of the interfer-ometer are described and comparisons with traditional interferometer about their spocifications aretransmit incident and reflective laser is introduced. The principle and the structure of the interferometer are described and comparisons with traditional interferometer about their specifications aregiven. The expeimental arrangements and results of measuring projectiee velocity of an electricsquib and the free-surface velocity of a tungsten target aregiven as well.Finally its functionsand specifications are summarized.
