Optical coherence tomography thesis
Optical coherence tomography (oct) is an optical imaging technique that provides depth-resolved imaging of biological tissue with high resolution generally, an imaging beam scans across the tissue surface to acquire a two- or three-dimensional image. These layers can be visualised using optical coherence tomography (oct) imaging the abnormalities in these layers are indications of several eye diseases that can lead to blindness, such as diabetic macular edema (dme), age-related macular degeneration (amd) and glaucoma. Optical coherence tomography (oct) is one such technology oct fills a niche between the high resolution of confocal microscopy and deep imaging penetration of ultrasound. Abstract this thesis presents an investigation on endoscopic optical coherence tomography (oct) as a noninvasive imaging modality, oct emerges as an increasingly important diagn.

Optical coherence tomography (oct) is an emerging optical imaging method, which allows the acquisition of cross-sections in a non-destructive and contactless manner today, oct systems provide axial resolutions ranging from 1 – 10 µm and allow real-time in situ and in vivo imaging. Optical coherence tomography (oct) is a non-invasive volumetric imaging technique that offers micron scale resolution over several millimetres of depth penetration in tissue the aim of the project was to develop full field swept source oct (ffssoct), charting. Optical coherence tomography (oct) is a relatively new imaging technique which is of great importance in the identification of ocular and especially retinal diseases thus, the efficient analysis of oct images provides several advantages. This thesis proposes and describes the use of optical coherence tomography (oct) as a non-contact and non-destructive characterization technique for printed electronics it is based on and. This thesis presents the first work, to our knowledge, to evaluate the potential of optical coherence tomography (oct) as an intravascular imaging modality to characterize and guide interventions on chronic total occlusions (ctos) in arteries.
Purpose optical coherence tomography (oct) is a rapidly evolving, robust technology that has profoundly changed the practice of ophthalmology spectral domain oct (sd-oct) increases axial resolution 2- to 3-fold and scan speed 60- to 110-fold vs time domain oct (td-oct. This thesis discusses certain aspects of the noninvasive imaging technique known as optical coherence tomography (oct) topics include three-dimensional image rendering as well as application of the fast fourier transform to reconstruct the axial scan as a function of depth.
