| dc.description.abstract | This paper proposes a real time damage identification method based on the perturbation analysis of the rotation field, which are measured using shearography technique. A particular case of phase modulation method is applied to the interference pattern in order to improve the spatial resolution of the rotation field. A program was developed in Matlab® platform for digital recording the information capture by CCD camera and post-processing the data using dedicated image techniques. The phase filter and unwrapping algorithms were optimized to allow the visualization at video rate the full-field rotations fields. For small internal damages in laminated composite plates, the results show a superior performance of the proposed technique in relation to the classical raw fringe analysis. | por |
