Abstract

Because of the accuracy needed in the operation of photo-optical systems of simulation, the present paper attempts to measure the differences in sensitivity of motion perception in the various portions of the retina. There is a noticeable difference between the central and peripheral retinal areas in the detection of angular movement and in threshold excitation. The peripheral area dominates the central area in motion detection because it has more rods, thus having a lower threshold excitation and a lower threshold of critical fusion frequency (c.f.f.). By measuring the c.f.f. gradient at varying visual angles on the nasal, temporal, inferior and superior coordinates, it was found that the peripheral area, specifically temporal area, has lower threshold to' motion perception than the central area.
