Optical coherence tomography

Optical coherence tomography (OCT) is a light-based examination technique providing high resolution cross-sectional views of objects which moderately absorb and scatter the probing light.

The technique is non-contact, non-destructive and does not require any preparation of the object examined. It is also used as a diagnostic technique by ophthalmologists to look at the layers of the retina at the back of the eye.
