Passage Two
Television was not invented by any one person. Nor did it spring into being overnight. It evolved gradually, over a long period, from the ideas of many people一each one building on the work of their predecessors．The process began in 1873，when it was accidentally discovered that the electrical resistance of the element lenium（硒）varied in proportion to the intensity of the light shining on it. Scientists quickly recognized that this provided a way of transforming light variations into electrical signals. Almost immediately a number of schemes were propod for nding pictures by wire（it was, of cour，before radio)．
One of the earliest of the schemes was patterned on the human eye. Sugested by G.R.Carey in 1875, it envisioned a mosaic of lenium cells on which the picture to be transmitted would be focud by a lens system. At the receiving end there would be a sim
ilarly arranged mosaic made up of electric lights．Each lenium cell would be connected by an individual wire to the similarly placed light in the receiving mosaic．Light falling on the lenium cell would reproduce the original picture. Had the necessary amplifiers（放大器、扩音器）and the right kind of lights been available,this system would have worked. But it also would have required an impractical number of connecting wires．Carey recognized this and propod to "scan" the cells一transmitting the signal from each cell to its associated light, in turn, over a single wire．If this were done fast enough, the retentive power of the eye would cau the resultant（合成的）image to be en as a complete picture.
