Paper Abstract
In order to study the metal target surface in-place deformation induced by the laser beam or other ones effecting upon, three kinds of measuring dynamic in-plane deformation techniques by means of a laser speckle, which are the speckle field time sequence processing (that is the optical flow analysis of speckle pattern), the digital speckle pattern processing (in fact, it is a kind of pattern or picture enhancement technique), and the digital speckle pattern correlation metrology, have been studded and developed. The latter, the correlation metrology, has been made a big progress: better precision and higher processing speed.
