摘要: 本文综合评述了光测力学的近况和发展,其中包括传统的光弹性法和云纹法,以及近代光测力学的全息干涉法、散斑计量和云纹干涉法。文中简要介绍了上述方法的基本概念和特点,并给出了若干工程应用的实例。

Abstract: This paper reviews the state-of-art and development of photomechanics, a major subject of experimental mechanics, in brief. The conventional photomechanics is essentially composed of photoelasticity and moire method. Modern optical method and laser technique advance the photomechanics to a new stage and bring about the emergence of modern photomechanics which comprises holographic interferometry, speckle metrology and moire interferometry. The methods of modern photomechanics have opened up the new field of research and application of photomechanics. The essential concepts and the features of the above-mentioned methods are described. In addition, some examples of their application to engineering, especially to aeronautics, are introduced in the paper.
