The iconoscope was an early electronic camera tube used to scan an image for the transmission of television. No other practical television scanning device prior to it was completely electronic, although some, such as the Nipkow disc, combined electronic elements with mechanical ones.
Why was the iconoscope so important?
The iconoscope produced a much stronger signal than earlier mechanical designs, and could be used under any well-lit conditions. This was the first fully electronic system to replace earlier cameras, which used special spotlights or spinning disks to capture light from a single very brightly lit spot.
Who developed the iconoscope?
Zworykin (the Iconoscope) in 1924 and by Philo T. Farnsworth (the Image Dissector) in 1927. These early inventions were soon succeeded by a series of improved tubes such as the Orthicon, the Image Orthicon, and the Vidicon. The operation of the camera tube is based on the…
When was the iconoscope patented?
While working for Westinghouse, Zworykin patented his first television camera tube in 1923 and his kinescope television receiver in 1924. In 1929, he went to work for RCA as Director of Electronic Research at its Camden, NJ, laboratory. He improved his television camera tube and then patented the iconoscope in 1931.
Who invented iconoscope camera tube?
One of the foremost figures in the complex history of television is Vladimir Zworykin (1889-1982), who invented the “iconoscope,” “kinemascope,” and “storage principle” that became the basis of TV as we know it.

What is in a cathode ray tube?
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, the beams of which are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms (oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena.
How did the iconoscope work?
The iconoscope was an early electronic camera tube used to scan an image for the transmission of television. ... An electron gun, also placed in the housing, projected a scanning beam of electrons toward the plate. Deflecting coils directed the electron beam, which charged the plate's pixels.
How did the image dissector work?
An image dissector, also called a dissector tube, is a video camera tube in which photocathode emissions create an "electron image" which is then scanned to produce an electrical signal representing the visual image.
How did television get its name?
The word television comes from the Greek prefix tele and the Latin word vision or “seeing from a distance.” The TV camera converts images into electrical impulses, which are sent along cables, or by radio waves, or satellite to a television receiver where they are changed back into a picture.

What were CRTs used for?
CRTs are used to produce images. The phosphors in a CRT's screen are the materials that directly produce the photons generated by the CRT. These phosphors are struck by incoming electrons from the electron gun, absorb energy, and then re-emit some or all of that energy in the form of light.
