摘要: 针对冲击爆轰实验中对速度测量系统的高可靠性要求，基于光纤波分复用/解复用技术，提出了一种双波长全光纤激光干涉速度复测方法及技术。设计并搭建了一套速度复测原理验证系统，采用
1530.3 和1550.0 nm 2个波长，在气体炮上开展了低速、高速2种典型状态下的动态验证实验。实验结果显示，利用单一光纤探头实现了样品自由面运动速度的复测，2个波长系统得到的速度测量结果具有较好的一致性，速度相对偏差在±1.5%以内。Abstract: In order to meet the high reliability requirement of velocity measurement in shock wave and detonation experiments, a new velocity measurement method named dual-wavelength laser interferometer was proposed based on wavelength division multiplexing/demultiplexing technique. A verification system was designed with1550.0 and1530.3 nm wavelengths, and the dynamic verification experiments under low- and high- speed conditions were carried out on the light gas gun. The dynamic experimental results show that the free surface velocity of the sample can be measured independently with a single optical fiber probe, and the velocity measurement results obtained at two wavelengths exhibit good consistency, with the relative deviation of the velocity within ±1.5%. -
