It was a electromechanical device based on the photoconductivity of the element Selenium and Nipkow's spinning disk with a series of holes of equal diameter drilled into it at equal distances. In the camera unit, as the disk spun in front of the object, each hole produced a scan line which was captured by a light detecting device behind it. The scan line was transmitted by radio wave to the reproducer or receiving unit. This basic television and other refinements that came after it were however restricted to transmission of still images and silhouettes.
