Small Field Of View

Moire´ interferometry is a full-field optical method that has high displacement, strain and spatial resolution. The method has been used extensively for deformation analyses in the various fields of mechanics. Special considerations arise when deformation measurements of tiny specimens or tiny regions of larger specimens are sought. The relative displacements within a small field of view will be small (even if the strains are not small), so the number of morie´ fringes might not be enough for an accurate analysis.

Deformation Measurements

This paper compares the technology and the performances of three ultra high speed cameras for full-field deformation measurements with Digital image correlation or the grid method. The three cameras are based on multiple CCD sensors (Cordin 550-62, with rotating mirror or DRS IMACON 200 with gated intensified CCDs) or dedicated chip (Shimadzu HPV). The advantages and limitations of these cameras are critically reviewed.
