ARTIFICIAL RETINAL PROSTHESIS SYSTEM, OPTICAL DEVICE AND RETINA CHIP

摘要

An artificial retinal prosthesis system comprises an extraocular optical device and an intraocular retina chip. The extraocular optical device receives an external image, converts it into an optical pulse signal, and generates light energy. The intraocular retina chip receives the optical pulse signal from the extraocular optical device and produces an electric simulation signal. The intraocular retina chip includes a solar cell module receiving and converting the light energy into electric energy as a power source of the intraocular retina chip. The artificial retinal prosthesis system uses an optical modulation method to convert an image signal into an optical pulse signal, transmits the optical pulse signal into the eyeball, and decodes the optical pulse signal intraocularly. Thereby, the signal light intensity is improved without affect the contrast ratio.
