Abstract
The image-forming properties of the human optical system have been examined with the aid of a photoelectric ophthalmoscope. The light distributions in images of bright vertical lines formed by a double passage through the eye optics were measured. On the assumption that the eye optics are reversible, the light distributions on the retina were computed by means of Fourier transforms. The results are also expressed in terms of the spatial frequency response functions for the eye. The effects of pupil size were examined. The best imagery was obtained with a 5-mm pupil. The results confirmed the earlier measurements on human eyes reported by Flamant. The more recent experiments on animal material by DeMott do not seem to be relevant to living human eyes.
