Abstract
A new optical link method for the retinal prosthesis is proposed. A laser diode system was chosen to transfer image into the eye and the new optical system was designed and evaluated in silico and ex vivo. The use of laser diode array in artificial retina system makes system simple by deleting signal processing part inside of the eyeball. The designed optical system is enough to focus laser beam on photodiode array in 20 × 20 application on simulation using Code V program, and about 200 μm focusing of laser beam was possible on experiment with porcine eye.
