Abstract
The retinal image quality in the human eye have been measured by using a hybrid optical digital method, consisting in the recording and processing of retinal images of a point test after reflection in the retina. The method allows one to obtain accurate data on the modulation transfer function of the eye, which can be directly used in vision research and practical optical engineering studies. The technique has been used to obtain image quality results both in the fovea and the periphery under different experimental conditions. These results have some implications to retinal sampling: in natural viewing the eye's optics provides a good protection against aliasing (spatial undersampling) in the fovea, but leaving the cone mosaic least protected at eccentricities around 10 to 20 degrees. Experimental systems based on this optical digital technique might have potential applications to obtain high resolution fundus images in the living eye.
