Paper Abstract

Contouring by electronic speckle pattern interferometry is one of the most difficult measuring problems in the range of micrometers. The requirement of the position alignment of the master wavefront (smooth or speckled) and the wavefront of the test object by interferometric accuracy is always a difficult task and prevents the application of this method for quality controlling. To overcome the difficulties, in our paper a new two-wavelength method is presented.
