Recently, in-vivo full field (FF) optical coherence tomography (OCT) with an ultra-high speed camera has been presented for fast in vivo retinal imaging. By parallel A-scans acquisition, imaging with 1,5 million A-scans/s was shown with an extended illumination of the retina. In this paper, the image quality of FF-OCT images will be compared to conventional scanning OCT systems. The effect of the absence of a confocal aperture leading to crosstalk between adjacent image points will be shown and an experimental analysis of the systems lateral point spread function (PSF) in dependence of depth will be given and discussed.
