Nipkow disk
Quick Summary
The Nipkow disk is a mechanical device that was crucial for early television technology. Invented by Paul Gottlieb Nipkow in 1884, it features a rotating disk with a spiral of apertures. As the disk spins, these apertures pass across an image, analyzing small portions of it successively. This process allowed for the transmission of light intensities, forming the basis of mechanical television systems. While groundbreaking, the Nipkow disk was eventually replaced by electronic scanning devices in 1934.123
