Simulation of Speckle Interferometric Results for Enhanced Measurement and Automated Defect Detection
Jessica Plassmann, Michael Schuth, Georg von Freymann
Techniques like speckle holography and shearography are rarely applied due to the complexity of instrument setup and lack of automated result analysis, despite their potential. By…
