| 中文摘要: |
| 进入21世纪之后，激光干涉作为一种成熟的非接触式动态测量技术，开始逐步应用于不同的工业领域。激光干涉动态测量技术主要分成两类：一类是基于高速相机的干涉测量技术，而另一类则是基于单像素光电探测器的干涉测量技术。这两类技术都有其局限性：基于高速相机的技术受限于相机时间轴上的采样率；而基于光电探测器的技术则在空间域上只能进行单点测量。针对稳态振动和非稳态振动/变形测量两种实际应用，本文分别讨论了这两类干涉测量技术近年来的一些最新发展。作者希望通过本文的讨论为不同领域的研究人员和工程师在实际应用中选取更优的动态测量方案提供有力的参考。 |
| 英文摘要: |
| Since the beginning of the 21st century, laser interferometry, as a mature non-contact dynamic measurement technology, has been applied to various industrial areas. It can be divided into two categories: high-speed camera-based and photodetector-based technologies, respectively. Both types of technologies have their own limitations: high-speed camera-based technologies are limited by the capturing rate; while photodetector-based technologies can only perform single-point measurements. Aiming at two practical applications of steady-state vibration and unsteady-state vibration or deformation, this review discusses some of the latest developments of both technologies. The authors hope the review would throw some light on the guidelines when the researchers and engineers in different areas choose better measurement solutions for various applications. |
