Abstract
Optical coherence tomography (OCT) is a new technique for noncontact, noninvasive cross-sectional imaging in biological systems.1 OCT uses low coherence interferometry to produce 2-D images of Fresnel reflections and optical scattering from internal tissue microstructures with high spatial resolution and high sensitivity. We have used OCT to perform direct measurements of ocular structure in the anterior and posterior eye. OCT is potentially useful as a noninvasive, quantitative, and early diagnostic for a number of diseases of the eye, including glaucoma and cataracts. OCT has also been used in image scattering systems such as the human coronary artery as well as non-biological systems such as multichannel lenses.
