为完全丧失视觉的盲人再造视觉,早在本世纪中叶已经有人进行探索。经科学家几十年努力,一种能让盲人鉴别面前的物景和活动的场面,能让盲人进行阅读文字和图像的电子眼实验模型已在10年前诞生,它的名称叫视皮层直接显像助视器。其主要结构包括摄像仪、中间处理计算机和视皮层植入器三部分。①摄像仪:即人工眼或称外感受器,是由包含144个光敏点的光敏元件组成的注 For the visually impaired blind people to recreate the vision, as early as the middle of this century has been explored. After decades of efforts by scientists, a scene that allows blind people to identify the scenes and activities in front of them, an electronic eye experimental model that enables blind people to read texts and images has been born 10 years ago. Its name is called direct visualization of the cortex. Vision aids. Its main structure includes three parts: camera, intermediate processing computer and visual cortex implanter. 1 camera: artificial eyes or external sensors, consisting of photosensitive elements containing 144 photosensitive dots
