Paul Gottlieb Nipkow
Was made in 1884. Made the first ever mechanical module tv. Was one of the first successful technologies for television. He did this by figuring out how light intensities of small portions of an image are successively analyzed and transmitted. In 1873, the photoconductive properties of the element selenium were discovered, the fact that selenium's electrical conduction varied with the amount of illumination it received. Paul Nipkow created a rotating scanning disk camera called the Nipkow disk, a device for picture analyzation that consisted of a rapidly rotating disk placed between a scene and a light sensitive selenium element. |
