Optical coherence tomography

Optical coherence tomography (OCT) has become a critical imaging tool in medicine owing to its noninvasive imaging capability of tissues with micrometerlevel details. From its initial experiments in the 1980s to now, the adoption of OCT has been facilitated not only by scientific innovations but also advances in fiber optic telecommunications and photonics, as well as industry and government support. This review highlights key milestones that have contributed to the clinical adoption of OCT, as well as current and future trends.
