Optical Coherence Tomography in Glaucoma
Journal of Current Glaucoma Practice, 2012 The optic disk and the RNFL are the principal sites of apparent glaucomatous damage which precedes glaucomatous visual field alterations. RNFL defects are known to precede detection of visual field defects by approximately 6 years. Accurate early detection and monitoring of ONH and RNFL defects has become the prime focus of effective management of ...

Speckle in Optical Coherence Tomography
Journal of Biomedical Optics, 1999 Speckle arises as a natural consequence of the limited spatial-frequency bandwidth of the interference signals measured in optical coherence tomography (OCT). In images of highly scattering biological tissues, speckle has a dual role as a source of noise and as a carrier of information about tissue microstructure.

Low-coherent optical diffraction tomography by angle-scanning illumination [PDF]
arXiv, 2018 We propose and experimentally demonstrate temporally low-coherent optical diffraction tomography (ODT) based on angle-scanning Mach-Zehnder interferometry. Using a digital micromirror device based on diffractive tilting, we successfully maintain full-field interference of incoherent light during every scan sequence.

The Development, Commercialization, and Impact of Optical Coherence Tomography
Investigative Ophthalmology and Visual Science, 2016 This review was written for the special issue of IOVS to describe the history of optical coherence tomography (OCT) and its evolution from a nonscientific, historic perspective. Optical coherence tomography has become a standard of care in ophthalmology,

Theoretical analysis of performance limitation of computational refocusing in optical coherence tomography [PDF]
arXivHigh-numerical-aperture optical coherence tomography (OCT) enables sub-cellular imaging but faces a trade-off between lateral resolution and depth of focus. Computational refocusing can correct defocus in Fourier-domain OCT, yet its limitations remain unaddressed theoretically. We model the pupil-based lateral imaging process to analyze defocus and the
