| Abstract: | Numerical display of inplane displacement measurement by electronic speckle photography is described. This technique is a realtime measurement. The speckle pattern is recorded by a CCD camera, and the discrete data are sent to the computer. The numerical display of the computer can yield better fringe pattern and displacement measurement value. Experimental results of small displacement for cantilever beam are given. The results have verified the correctness of this technique. |
