%X 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.
