章节摘录

　　One of the earliest of these schemes was patterned on the______eye. Suggested by G. R. Carey in 1875， it imagined a mosaic （感光） of selenium cells9 ， on which the picture to be______would be focused by a lens system. At the receiving end there would be a similarly arranged mosaic made up of elec tric lights. Each selenium cell would be connected by an individual wire to the similarly placed light in the receiving mosaic. Light______ on the selenium cell would cause the associated electric light to shine in proportion. Thus the mosaic of lights would______the original picture. Had the necessary amplifiers（放大器） and the right kind of lights been available， this______ would have worked. But it also would have required an impractical number of connecting wires. Carey recognized this and in a second______proposed to "scan" the cells transmitting the signal from each cell to its associated light， in turn， over a wire. If this were done fast enough， the holding power of the eye would______the transmitted image to be seen as a complete picture.
