RT Journal Article T1 Enhancement of surface inspection by Moiré interferometry using flexible reference gratings A1 Quiroga Mellado, Juan Antonio A1 Martínez Antón, Juan Carlos A1 Canabal Boutureira, Héctor Alfonso A1 Bernabéu Martínez, Eusebio A1 Álvaro Labajo, M. A1 Cortés Testillano, V. AB We have extended the use of shadow Moiré technique to be implemented in simple curved surfaces by using a flexible grating. Dynamic visual inspection of surface micro-damages is significantly favored by the use of well adapted pliable gratings compared to the use of flat reference gratings. The experimental set-up consists of a plastic foil with a printed Ronchi grating stretched between three points which adapts to any cylindrical or conical convex surface independently of the relative orientation grating/surface. Static quantification of defects profiles is also possible with an attached CCD camera. Visual detection of defects in the range of ~30 μm in depth is obtainable.
