25 years of OCT

SPIE Classics celebrates 25 years of research and development in optical coherence tomography.

10 January 2018

Since its inception more than 25 years ago, optical coherence tomography (OCT) has become a major medical imaging technology and is particularly well established in ophthalmology.

In the intervening years, research activity into the underlying devices,subsystems, methods, and techniques of OCT has continued to grow.

OCT remains true to the spirit of the broader field of biophotonics itself, with a focus on practical engineering to tackle practical challenges. Despite the maturity of research in some areas, others remain relatively unexplored, and technical advances are opening new doors.

To celebrate the 25-year milestone of this technology, the SPIE Journal of Biomedical Optics recently published a special section focusing on OCT applications in medicine and biology.

The papers, now available in the SPIE Digital Library, reinforce the perspective that OCT as a research topic is vibrant and strong, with many new opportunities in the wings waiting for clinical and commercial primetime.
