MANU BAIRD,John,Logie circa 1925 Hastings, East Sussex, The Baird television system was electromechanical in nature. To transmit an image, a light source was focussed onto the scanning disc (interrupter) which was driven by a motor. The light passing through the disc illuminated the object in numerous vertical strips, every tenth of a second. This light was reflected from the object to a photo-electric cell. The output from the cell was then transmitted to the receiver, which was coupled to a neon glow lamp, the light from which was passed through a condensing lens and then another disc. It was then directed to a screen where the image was constructed. This disc has a row of thirty six radial slots cut in its circumference, and 96 small round holes. This example is not a Nipkow disc, | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
