In this research, first through experimental studies, the recorded signals associated with the light white from human retina cells were digitized, then the digital data were calculated and the resulted mathematical equation was programmed on a microcontroller, and by designing a circuit, the output voltage over time similar to initial signals associated to the white light was obtained.This circuit can be designed and implemented on an IC, which can be planted on retina cells, so that the brain can receive signals analogous to the signals associated with the white light.

Keywords: retina; nervous signals; optical receivers.
