SUMMARY
An arrangement in Digital Holographic Interferometry (DHI) is presented for simultaneously 2D measuring micro deformations in the surface of optically rough objects. For this arrangement a 3CCD color camera and two laser sources 458nm and 633nm were used, this allows to record two digital holograms simultaneously. The arrangement is tested on a metal plate which is slightly microscopically deformed when heated by a soldering iron. The experimental results show the metrological potential of the system for mechanical quantities characterizing the structure of the object.
