Abstract

Current state-of-the-art human retinal vis-OCT systems have a limited field of view due to the large curvature of the retina and the system sensitivity roll-off. Here we presented the first linear-in-k visible range OCT spectrometer and achieved a sub-5dB roll-off over the entire imaging depth. The first full-range vis-OCT imaging was demonstrated to extend the system imaging depth. Thanks to 140 nm bandwidth in visible light range, the system axis resolution can achieve 1-2 um in air and a 65˚ by 65˚ wide-field human retinal full range vis-OCT imaging was demonstrated.
