Nipkow disk - Wikipedia, the free encyclopedia A Nipkow disk is a mechanical, geometrically operating image scanning device (by itself, it performs neither image acquisition or reproduction), invented by Paul Gottlieb Nipkow, which was primarily used as a fundamental component in mechanical television. Another serious disadvantage when reproducing images with the aid of a Nipkow disk, is that the images are typically very small, as small as the surface used for scanning, and which on the practical implementations of mechanical television was the size of a postage-stamp, for a 30 to 50 cm diameter disk. In fact, the Nipkow disks used in early TV were roughly 30cm to 50cm in diameter, with 30 to 50 "holes". en.wikipedia.org /wiki/Nipkow_disk   (792 words)

Paul Gottlieb Nipkow - Wikipedia, the free encyclopedia It is not known whether Nipkow ever attempted a practical realization of this disk but one may assume that he himself never constructed one. Nipkow took a position as a designer in a Berlin-Buchloh institute and did not continue work on picture broadcasting. Nipkow recounted his first sight of television at a Berlin radio show in 1928: "the televisions stood in dark cells. en.wikipedia.org /wiki/Paul_Gottlieb_Nipkow   (489 words)

Paul Nipkow was the first person to discover television's scanning principle, in which the light intensities of small portions of an image are successively analyzed and transmitted. 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. www.biologydaily.com /biology/Paul_Gottlieb_Nipkow   (391 words)

By the beginning of the 1930's electronic picture scanning, based on the iconoscope invented by Wladimir Kosmitsch Sworykin, was prevalent and Nipkow's invention ceased to have direct relevance. It was an appropriate gesture, but one excessively exaggerated; Nipkow became honorary president of the "television council" of the "Reich Broadcasting Chamber" -- a "German television-pioneer" who long before had dreamed up an method of broadcasting he did not implement. www.recipeland.com /encyclopaedia/index.php/Paul_Gottlieb_Nipkow   (544 words)

Paul Gottlieb Nipkow Biography / Biography of Paul Gottlieb Nipkow History of Invention Biography Nipkow, now considered the forefather of the television age, received little recognition for his contribution during his lifetime. Nipkow was born on August 22, 1860, in Lauenberg, Germany. Nipkow's television was based upon an ingenious device called a Nipkow disk, which was a metal or cardboard disk that was perforated with twenty square holes arranged in a spiral so that each hole was a little closer to the center than the last. www.bookrags.com /biography-paul-gottlieb-nipkow-woi   (551 words)

Another serious disadvantage when reproducing images with the aid of a Nipkow disk, is that the images are typically very small, as small as the surface used for scanning, and which on the practical implementations of mechanical television was the size of a postage-stamp, for a 30 to 50 cm sized disk. Apart from the aforementioned mechanical television, which never took off the ground for the practical reasons mentioned above, a Nipkow disk is used in one type of confocal microscope, a powerful optical microscope. www.reference.com /browse/wiki/Nipkow_disk   (775 words)

The official DANCAD3D (tm) Beta Test Web site. When manufacturing Nipkow disks high precision is required for the centering and location of the holes. Having the holes drilled or punched to high tolerances is especially important when using the Nipkow disk for autostereoscopic displays since dislocation of the pixels may introduce errors in the stereoscopic depth perception. My interest in the Nipkow scanning disks primarily arises from my past and continuing interest in the design of autostereoscopic video displays that have many of the properties of Holographic video displays, see the information about my published papers below. www.dancad3d.com /S0911500.HTM   (1822 words)
