众所周知,人类借助视觉器官接收周围世界信息。那么,能否用电子学的方法恢复视力使盲人“看见”东西? 有的科学家认为,用特殊的超袖珍电视摄影机将所接收的映像变为电脉冲,电脉冲通过电极对大脑视觉中心发生作用。有的科学家提出,利用触觉途径达到对大脑映像信号的转换。在形成光栅时,“看见”图像的特殊装置把映像信号分散到单个点上。经过专门的转换器,进入固定在人皮肤的感光板上。信号大小,取决于每个点的亮度。感光板由400个聚四氟乙“小棒”组成,这些“小棒”能按照从光栅点传来的信号大小,贴着皮肤振动和碰撞。由于这些特殊力的刺激,人如同“感觉”到映像。科学家认为,用触觉器官接收光的图像并不很
It is well-known that humans use visual organs to receive information about the world around them. So, can electronics blindly blind people to “see” something? Some scientists think that using a special super-compact TV camera will receive the image into electrical pulses, electrical pulses through the electrode on the role of the brain’s visual center . Some scientists propose to use the tactile approach to convert the brain imaging signal. When forming a grating, special devices “see” the image to spread the image signal to a single point. After a special converter, into the fixed in the skin of the photosensitive plate. The signal size depends on the brightness of each point. The plate consists of 400 polytetrafluoroethylene “sticks” that vibrate and collide with the skin in response to the signal from the grating point. As a result of these special forces, people feel “like” to the image. Scientists believe that the tactile organs to receive the light image is not very good
