Image degradation by an irregular retinal mosaic

摘要

In order to understand the significance of a regular photoreceptor mosaic we quantify the effect of deviations from regularity. Such deviations are shown to cause a deterioration in the quality of the image at the photoreceptor level because of image demodulation and image distortion. Consequently, a regular receptor array is necessary for extracting all of the spatial information available in the retinal image.
