TV History The mechanical part consists mostly of a mechanical Nipkow disk, which has several holes in a spiral path. The bedroom is the disk is a device sensitive to light, usually behind a light barrier. Player (display), a modulated light source, usually a neon tube, and the light sensor. Each hole in-the-fly generated to look for a line. AM radio or scan CCTV implementation model reproducer.Block system.Facsimile mechanical scanner still images from the early mechanical television uses the early 1800s. For example, Shelford Bidwell has shown how the system in 1881. For decades, the scanning system was the first pioneer in the broadcasting and the drawings. Download the images was a challenge. Selenium photocells at the beginning of a very low sensitivity. Scan resolution of the image is suitable for newspaper reproduction, it can take several minutes. With a two-tone silhouette images and immediate access to a modern image to the TV thanks to a copy of the head 1909.Baird "Bill Stooky" dolls similar to JL Baird in his early experiences with television. Paintings, probably comparable to quality.In 1920, Yasujiro Niwa Japanese scientists invented a simple device and cable broadcasts and radio, and then photo telegraphic. American inventor Charles Francis Jenkins has developed a mechanical television in 1920 and 1930. In 1923 Jenkins sent the first form of moving images and 13 June 1925 showed that the image of public television and transmits a live sync sound.Mechanical image colors (gray) by British inventor John Logie Baird 26th January 1926 is shown in his laboratory in London. Unlike later electronic systems for hundreds of lines of vertical resolution of the scanned image Baird, scan the hard drive integrated with a double spiral of lenses, had only 30 lines long enough to have a face. Why identify the man, only a limited number of holes and washers in a certain diameter has become impossible, resolution of the images on television, was a mechanic in the usually very low, 30-120 lines or less. Some systems are 200 parts of the network is in the air. Two of them are 180 rows of counters and the Company (CDC), which was founded in Paris in 1935, Peck and 180 lines in 1935, the station began Montreal.Instead VE9AK Nipkow disc, an engineer, other TV technologies have. Other agreements are often a rotating drum, then a row of holes or reflects them. another scanner scanning method is the place to fly ", instead of flying. "Cruise business has developed to the lack of sensitivity of the photodetector, which is at that time. Ray of Light, the light through the narrow openings Nipkow disk seems correct. The light is a problem of light TV, in the dark studio. Whipping and continue up and down, a point of light, or more than sixteen times per second. light is reflected not just one, but the bank photocells combined. the signals from these cells was a strong image. mechanically, like television, is that Bush flies this image transmission technology (fax). This assay, like the BBC 1800s.The point to 1935, was flying. German television methods instead of flying until 1938. This year, at the end of the flight-tech scanner inventor. German Manfred von Ardenne, the scanner, instead of flying cathode ray tube as a source of light. In 1950, Dumont sold Vita scan, a full test flight of the color. Today, scanner, graphics, navigation still using this method. Flying spot method has two disadvantages: The players are working in the dark, and flying machines tend outdoors in well-known TV daylight.A unstable by the scanner instead of a leak Ray Kell work in 1928, the General Electric scanner instead of the United States showed that the fly can be used outdoors. Scanning light source should be clear that other accidents illumination.Kell an engineer who was the camera that the images are 24 lines of the New York governor Al Smith, was Smith .
