Quantum tech gives high-resolution OCT

Follow the development of the highest-resolution OCT system ever built.

If you are interested in quantum technology or optical coherence tomography (or both), you might want to follow the SEQUOIA project – the project combines the two and aims to develop a quantum OCT system.

OCT is a non-invasive imaging technique that uses light to capture real-time, high-resolution, cross-sectional images of biological tissue. It can be used for diagnosis, treatment planning, monitoring of medical conditions, and much more.

The highest-resolution OCT system ever built

SEQUOIA is a European project under the Horizon Europe program. Eleven European institutes and companies are working together to develop the highest-resolution optical coherence tomography (OCT) system ever built. To reach this goal, SEQUOIA will use quantum techniques to design an ultra-high-resolution quantum OCT system (QOCT).

Today, the best OCT systems have a 1-micron axial resolution. With the quantum OCT system, SEQUOIA aims to reduce the axial resolution to 0.5 microns.

SEQUOIA will use retinal imaging as a test case.

An ultra-stable light source is the heart of the system

NKT Photonics is supplying the ultra-stable light source that is the heart of the quantum OCT system. We have based the light source on our renowned supercontinuum sources that give the ultra-low-noise comb source its broad bandwidth, spanning from 250 to 400 nm.

Advanced stabilization in collaboration with world-leading experts PTB will provide record low noise supercontinuum.
