An artificial retinal prosthesis system comprises an optical device and a retina chip. The optical device is used to receive an external image and convert it into an optical pulse signal and produce a luminous energy. The retina chip is used to receive the optical pulse signal from the optical device and produce an electric simulation signal. The retina chip comprises a solar cell module to receive and convert the luminous energy into electrical energy to provide power. The artificial retinal prosthesis system use the method of optical modulation to convert the image signal into optical pulse signal and decode thereof intraocular, such that the signal light intensity may be improved without affect the contrast ratio.一種人工視網膜系統,包含:一眼外光學裝置以及一眼內植入晶片。眼外光學裝置用以接收外部影像並將其轉換為光學脈波訊號及產生光能。眼內植入晶片用以接收自眼外光學裝置傳入之光學脈波訊號以產生電刺激訊號,眼內植入晶片並具有太陽能電池模組以接收光能並轉換為電力以作為眼內植入晶片之電源。此人工視網膜系統使用光學調變方式,將影像資訊轉換為光學脈波訊號傳入眼內再進行解碼,可提高訊號光強度且不影響訊號對比度。100‧‧‧眼外光學裝置101‧‧‧影像擷取模組102‧‧‧第一訊號處理模組112‧‧‧影像編碼模組122‧‧‧發光二極體模組200‧‧‧眼內植入晶片201‧‧‧第二訊號處理模組202‧‧‧第三訊號處理模組203‧‧‧太陽能電池模組211‧‧‧光偵測模組221‧‧‧訊號解碼模組301‧‧‧外部影像302‧‧‧影像訊號303‧‧‧發送訊號304‧‧‧光學脈波訊號305‧‧‧電訊號306‧‧‧控制訊號307‧‧‧電刺激訊號308‧‧‧電力1000‧‧‧人工視網膜系統
