Optical coherence tomography (OCT) was recently developed as a noninvasive diagnostic tool for use in biomedical imaging. We recognized that high dynamic range and optical gating characteristics make OCT an excellent tool for subsurface imaging in some highly scattering materials such as ceramics. Here we review the advances in OCT and other related promising optical gating techniques. We demonstrate the use of OCT in the imaging of the near-surface regions of ceramics and other materials. New applications and experimental results are presented. © 2000 American Institute of Physics.
