| 近40年来，由于激光的出现，使光力学测试的理论和技术有了快速的发展，测试技术丰富多彩。特别是数字图像处理硬件和软件的飞速发展，使光力学方法成为了常规的技术，在基础研究的探索和解决工程实际问题中，都发挥了重要的作用。本文对该阶段的主要进展，做一个简要的回顾。上世纪60年代激光的问世推动了光测实验力学的发展；70~80年代光测方法的发展着重于信息获得方面；90年代以后，数字图像处理技术的迅速发展,在信息提取的能力方面有了质的变化。如今，光测实验力学不仅灵敏度大大提高，而且已发展为常规的测试手段和现场测试技术。 |
| 英文摘要: |
| In recent 40 years, the theory and technology of photomechanics testing have developed quickly due to the laser emergence. A variety of testing techniques appeared. Especially, after wide application and high speed development of digital image processing hardware and software, the photomechanics technology became a routine testing means for fundamental exploration and solution of practical problems in engineering and played an important role. A brief review of major development of photomechanics in this stage is presented in this article. The laser emergence in sixties of last century promoted the development of optical measurement of experimental mechanics. The development of optical measurement in seventies and eighties of last century was focused on information acquisition. After nineties, the information acquisition ability presented a qualitative change due to the high speed development of digital image processing techniques. Now, the optical measurement of experimental mechanics not only has high sensitivity, but also becomes a routine testing means and a spot testing technique. |
