Correction of the Aberrations of the Eye Using Adaptive Optics with Pupil Tracking
(2011-09-01)Adaptive optics has long been used in the astronomical telescopes to acquire high resolution images via the real time correction of the rapidly changing wavefront aberrations. Human retinal images also suffer from rapidly ... -
A fibre based quad-cell wavefront sensor for high speed adaptive optics
(2014-05-20)The genesis of this thesis came out of the difficulties encountered when trying to apply adaptive optics correction to optical fields that contain scintillation (specklelike amplitude fluctuations). These scintillated ... -
High Resolution Flood Illumination Retinal Imaging System with Adaptive Optics
(2012-07-16)Retinal imaging has its advantages both in the research laboratory and medical applications. Acquiring high resolution in-vivo images of the retina requires some form of correction for aberrations. To address that, the ... -
Pre-processing, Registration and Quality Assessment of Adaptive Optics Assisted Retinal Images
(2014-01-27)In recent decades, adaptive optics (AO) technology has been embedded into retinal imaging devices, producing a new generation of instrument, which can provide retinal images with cellular resolution. This new technological ... -
Processing of adaptive optics photoreceptor images and application to the study of healthy and diabetic retinas
(2017-11-17)The introduction of adaptive optics (AO) into vision science has made it possible for clinicians to study the human retina in vivo with high-resolution images. The study of AO images of the cone photoreceptor mosaic is ... -
Spatio-Temporal Visual Response for Ocular Correction of Higher-Order Aberrations
(2013-04-24)With the development of control aberration using adaptive optics (AO), particular emphasis has been given recently to the impact of higher-order aberrations (HOAs) on visual performance, with a view to improved refractive ...
