Researchers achieve meter-scale optical coherence tomography for first time

An industry-academic collaboration has achieved the first optical coherence tomography (OCT) images of cubic meter volumes. With OCT’s ability to provide difficult-to-obtain information on material composition, subsurface structure, coatings, surface roughness and other properties, this advance could open up many new uses for OCT in industry, manufacturing and medicine. The achievement also represents important progress toward developing a high-speed, low-cost OCT system on a single integrated circuit chip.
