#ndt Optical coherence tomography (OCT), the most widely used optical medical imaging technology, has finally made its move into the non-destructive testing (NDT) and inspection arena, much as ultrasound did in the 1960’s. Valued for its ability to provide non-contact imaging of surface morphology and subsurface structure with micron-level resolution, the technique can provide quantitative analysis of structure, features, and defects for a wide range of materials. It is also rapid; 3D images may be captured in w
