| Abstract: | The improvement and application of a novel optical measurement technique-shearography are presented. This improved measurement is a laser-based technique for full-field, non-contacting measurement of 3D surface deformation and profile,and its structure and arithmetic are simpler compared with the conventional method. Other applications of shearography include surface strain and stress measurement, material characterization, residual stress evaluation, surface leak detection and 3-D surface shape measurement. |
