Optical coherence tomography introduction layperson's explanation theory optical coherence tomography is an established medical imaging technique and is used across several medical specialties including ophthalmology and cardiology, and is widely used in basic science. Optical coherence tomography andre j witkin michael ip jay s duker introduced in 1991, optical coherence tomography (oct) is a new technique for the high-resolution cross-sectional imaging of various ocular structures with an axial resolution of 10 microns. 1 introduction optical coherence tomography (oct) was first reported in 1991 as a non-invasive, cross-sec‐ tional ocular imaging technology (huang et al, 1991) and today is the most promising noncontact, high resolution tomographic and biomicroscopic imaging device in ophthalmology. Since its introduction as a diagnostic instrument, optical coherence tomography (oct) has become an essential instrument for ophthalmologists as it offers accurate details on both the vitreoretinal interface and the retinal layers. Introduction to optical coherence tomography oct is a high-resolution optical imaging technique that is based on the interference between the signal from the object being investigated (the sample) and a local reference signal oct can produce a cross-sectional image of an object in real time.

Optical coherence tomography has been used for a number of applications such as biomedical and materials research for the past decade. Optical coherence tomography - introduction introduction starting from white-light interferometry for in vivo ocular eye measurements imaging of biological tissue, especially of the human eye, was investigated by multiple groups worldwide. Optical coherence tomography background optical low-coherence interferometric techniques for applications in bio-imaging optical techniques play a significant role in medicine as they promise safe and low-cost solutions to many problems. Optical coherence tomography was first introduced commerically by carl zeiss in 1996 the first commerically available oct was based on time-domain technology (td) the stratus td-oct (carl zeiss meditec, usa) can scan resolutions up to 10 microns.
