A partially coherent imaging system distorts images nonlinearly. We investigate the restoration of such images by use of a second-degree nonlinear filter which is optimum for low-contrast images. The performance of this filter is shown to be better than that of a linear inverse filter, especially as the imaging becomes more coherent.
PURPOSE The goal of this study was to evaluate the ability of our handheld optical coherence tomography (OCT) scanner to image the posterior and anterior structures of the human eye, and especially the individual layers of the retina, and to compare its diagnostic performance with that of a fixed desktop commercial ophthalmic OCT system. METHODS We(More)
Optical coherence tomography (OCT) has long been used as a diagnostic tool in the field of ophthalmology. The ability to observe microstructural changes in the tissues of the eye has proved very effective in diagnosing ocular disease. However, this technology has yet to be introduced into the primary care office, where indications of disease are first(More)
