Early television experiment at the General Electric Co, 1928. A young lady poses as her picture is transmitted by means of photoelectric cells projecting from the apparatus directly in front of her during an early experiment with television. Video camera tubes in the early days of television used the photoelectric effect. Philo Farnsworth's Image dissector used a screen charged by the photoelectric effect to transform an optical image into a scanned electronic signal. | |
