2. Cathode-ray tube - Wikipedia

   en.wikipedia.org/wiki/Cathode-ray_tube

   A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. [2] The images may represent electrical waveforms on an oscilloscope , a frame of video on an analog television set (TV), digital raster graphics on a computer monitor , or ...

3. Cathode ray - Wikipedia

   en.wikipedia.org/wiki/Cathode_ray

   Cathode ray. A beam of cathode rays in a vacuum tube bent into a circle by a magnetic field generated by a Helmholtz coil. Cathode rays are normally invisible; in this demonstration Teltron tube, enough gas has been left in the tube for the gas atoms to luminesce when struck by the fast-moving electrons. Cathode rays or electron beams (e-beam ...

4. Flying-spot scanner - Wikipedia

   en.wikipedia.org/wiki/Flying-spot_scanner

   A flying-spot scanner (FSS) uses a scanning source of a spot of light, such as a high-resolution, high-light-output, low-persistence cathode ray tube (CRT), to scan an image. Usually the image to be scanned is on photographic film, such as motion picture film, or a slide or photographic plate. The output of the scanner is usually a television ...

5. CRT projector - Wikipedia

   en.wikipedia.org/wiki/CRT_projector

   A CRT projector is a video projector that uses a small, high-brightness cathode ray tube (CRT) as the image generating element. The image is then focused and enlarged onto a screen using a lens kept in front of the CRT face. The first color CRT projectors came out in the early 1950s. Most modern CRT projectors are color and have three separate ...

6. Cathode-ray tube amusement device - Wikipedia

   en.wikipedia.org/wiki/Cathode-ray_tube_amusement...

   The cathode-ray tube amusement device consists of a cathode-ray tube (CRT) connected to basic oscilloscope type circuitry with a set of knobs and switches. The device also incorporates very simple analog circuitry and does not use any digital computer or memory device or execute a program. [1] The CRT projects a spot on the display screen ...

7. Storage tube - Wikipedia

   en.wikipedia.org/wiki/Storage_tube

   Storage tube. The Tektronix 4014 uses a storage tube for its display. Storage tubes are a class of cathode-ray tubes (CRTs) that are designed to hold an image for a long period of time, typically as long as power is supplied to the tube. A specialized type of storage tube, the Williams tube, was used as a main memory system on a number of early ...

8. Werner Flechsig - Wikipedia

   en.wikipedia.org/wiki/Werner_Flechsig

   The patent title was "Cathode Ray Tube for the Development of Multicolored Pictures on a Fluorescent Screen." [3] An exhibit at the 1939 Internationale Funkausstellung Berlin displayed a prototype of Flechsig's color television receiver. [4] The war put an end to technical implementation of Flechsig's shadow mask picture tube.

9. John Bertrand Johnson - Wikipedia

   en.wikipedia.org/wiki/John_Bertrand_Johnson

   John Erik Bertrand Johnson (October 2, 1887 – November 27, 1970) (né Johan Erik Bertrand) was a Swedish-born American electrical engineer and physicist. He created the first cathode-ray tube oscilloscope and detailed a fundamental source of random interference with information traveling on wires, now called Johnson–Nyquist noise.
