Abstract
Optical Coherence Tomography (OCT) is a diagnostic imaging technique based on optical reflectometry, which is able to acquire high resolution in vivo images from transparent or semi-transparent tissues with a penetration depth of 2–4 mm and a resolution similar to a low power microscope. It is a non-contact, non-invasive imaging technique used to obtain high-resolution cross-sectional images of the ocular structures. OCT imaging of the retina or optic nerve head resembles a cross-sectional biopsy of the tissues of interest. Instead of viewing a stained section under a microscope, the clinician is presented with a ‘false-color’ view of the tissue at micron-level resolution. This chapter summarizes the basics and technical principles of the OCT systems including the time-domain, spectral-domain and swept-source OCT systems.
