双波长全光纤激光干涉速度复测技术
Dual Wavelength All-Fiber Laser Interferometric Velocity Retest Technique
摘要
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 with 1 550.0 and 1 530.3 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%.关键词
