Paper Abstract

For sometime now, holographic interferometry (HI) has been in use as a nondestructive inspection (NDI) tool at many manufacturing facilities. However, because of its sensitivity to external vibrations, the technique's full potential as a quality control tool cannot be realized in total. To overcome this problem, another technique called shearography is being explored by many. Unlike holography, shearography is immune to environmental vibration. In this presentation, we will explore the principle behind shearography, its applicability as an NDI tool and how it can be adapted to carry out on-site inspection.
