Digital Color Stimulator for Vision Research

摘要

Based on the optical principle of indirect oph-thalmoscopy an initial setup of a digital color stimulator for investigations of functional processes in the human retinal and visual system was realized. The stimulator combines the technique of classical flood illumination fundus imaging with spatio-temporal color projection onto the retina. The intention of electrophysiological application required some additional features of the setup including stimulation paradigms according to measure visual-evoked cortical potentials (VEPs).
