Optical Coherence Tomography (OCT) is an interferometric laser-based ranging modality which has dramatically impacted patient care in medical applications, but also has growing recognition as a valuable tool for industrial applications including PCB inspection, additive manufacturing, laser welding, and 3D metrology.

OCT is non-destructive and high-resolution like CT imaging, but more cost-effective.  It is insensitive to external illumination and surface characteristics, unlike photographic approaches.  And it provides both topographic and tomographic (cross-sectional) image data, unlike traditional laser ranging or structured illumination tools.  Fiber optic delivery of the interrogating beam allows OCT to be deployed remotely into harsh manufacturing environments.

Excelitas Technologies provides a flexible and scalable OCT platform through its AXSUN brand of laser engines and data acquisition devices:  simultaneous high resolution, imaging speed, and ranging depth are combined with plug-and-play connectivity, broad scanner compatibility, portability, and low power consumption.
