Abstract
To prove the possibility of detecting internal inhomogeneities in thick walled structures by holographic interferometry we measured the deformations of the outer surface of a thick walled pressure vessel above an internal weld point. The measured deformations were confirmed by calculations of the deformation field by the method of finite elements.
