Transatlantic BelinogramIn 1921, a facsimile was transmitted by radio across the Atlantic Ocean using the Belinograph invented by Eduard Belin. A written message from the managing editor of the New York Times was scanned by the equipment and sent by radio from Annapolis, Md., within seven minutes to Belin's laboratories at La Malmaison, France. The image received demonstrated that thereafter photographs could be scanned for radio transmission in the same way. The method was already in use within Europe sending photographs by wire. The original, wrapped on a rotating cylinder was scanned by a light beam reflected onto a photcell to convert the variations in the received intensity to electrical signals forwarded by radio or telephone wires.*«[Image: view a photograph wrapped on the cylinder of a Belinograph; year unknown.] |
