A Proposed Design for 3D-Measurements of the CFF Producing Spatial Distribution over the Retina

Article scientifique 2022 Anglais

Résumé

Abstract The average value of the critical fusion frequency (CFF) of the human eye is not only essential for the modern technological applications but also to the psychophysics of image recognition. The present work introduces a non-invasive technique that can scan the hemispherical visual field determining the CFF response to either chromatic or monochromatic light sources. The proposed design is an automated one such that a 3-D RS is performed, hence obtaining a retinal spatial distribution (RSD) of the CFF. The data is electronically stored, analyzed and plotted. The results obtained, show that the CFF for white light sources; is almost independent on the image location on the retina. On the other hand, the CFF values of chromatic sources namely (red, green and yellow) show strong dependence on the spatial position of the image on the retina. No appreciable dependence on the gender is observed; while the average values of CFF drop significantly with age.
