F—P激光多卜勒速度计的发展已有十多年的历史,其用途愈来愈广。由于应力波的深入研究和这种测速诊断技术的发展,使它在研究材料的弹塑性波双波结构方面、测量加载或卸载时的Hugoniot弹性限和测量材料产生层裂时强度等方面显现了明显的好处。因为自由表面速度的变化是一个非常灵敏的量,它可以反映出材料的许多重要变化。力学研究和多光束激光干涉技术的发展,促进了这个诊断技术的不断发展。 F-P laser Doppler speedometer has been the development of more than 10 years, its use is more and more widely. Due to the in-depth research of stress wave and the development of this diagnostic technology, it has been used to study the elasto-plastic wave dual-wave structure of materials, to measure the Hugoniot elastic limit when loading or unloading, Obvious benefits. Because the change in free surface speed is a very sensitive amount, it can reflect many important changes in the material. The development of mechanics and multi-beam laser interferometry has led to the continuous development of this diagnostic technique.
