Paper Abstract

Commonly, in-plane sensitive arrangements use tow symmetrical collimated wavefronts for object surface illumination. However, this is a limitation when large objects surface have to be analyzed. In this case spherical illumination is needed. Using this kind of optical set-up, the present work shows results of fracture measuring by using moire and speckle interferometric methods. Non- collimated symmetrical dual-beams, having a sensitivity vector varying with the position are performed. These methods are capable of detecting in-plane and out-of-plane deformations due to the use of divergent beams. It is calculated the error to each component of the sensitivity vector. Experimental result of fracture measurements are shown.
