The push for high-speed, high-resolution OCT

Optical coherence tomography (OCT) is already indispensable in ophthalmology, but its utility will grow further with improvements in resolution and speed.

Optical coherence tomography (OCT) is already indispensable in ophthalmology, but its utility will grow further with improvements in resolution and speed. Work in these areas is underway by a number of research groups, as was evident at the recent OCT symposium at Harvard Medical School/Massachusetts General Hospital (MGH). There, for instance, Axsun Technologies presented a poster on the impact of swept-source lasers with high tuning rate and broad tuning bandwidth for high-performance clinical systems. And OCT pioneer James Fujimoto emphasized speed in his presentation, which echoed the work presented in an article he co-authored for BioOptics World: Improved OCT imaging with VCSEL technology. A second piece in the same issue describes another approach to speedy OCT, with researchers at the University of Washington discussing an improvement to spectral-domain (SD-OCT) technology.

For even more on the topic of fast OCT, see "The multi-megahertz approach to optical coherence tomography" by researchers at Ludwig-Maximilians University (Munich, Germany), and Laser Focus World’s recent article, "OCT advances into clinical applications" by researchers at the University of California-Irvine.

The effect of all this work will be not only an expansion of OCT’s usefulness, but surely also greater adoption of OCT for such applications as endoscopy, dermatology, and dentistry.
