- Édouard Belin
Édouard Belin was born in
Vesoul onMarch 5 ,1876 , and died onMarch 4 ,1963 inTerritet (Canton of Vaud ,Switzerland ).He is the inventor in 1907 of the
phototelegraphic apparatus , a system able to send remotephotographs , via telephone and telegraphic networks. Since 1914, a photograph of report is transmitted by telephotograph.Its process was improved in 1921, so that it was able to transmit the images by
radio waves .In this apparatus, the transmitter traverses the original image point by point, and measures the light intensity via an electric eye. The intensity is conveyed to the receiver. There, a source of light reproduces the intensities measured by the electric eye, while carrying out same displacements exactly. By doing this, it impresses photographic paper, which makes it possible to obtain a copy of the original image.
The modern
telecopiers andphotocopiers use the same principle, with this close the sensor of light intensity was replaced by a sensor CCC, and that the device of impression is based on the laser technology, and either photographic.Belin was a president of the French Company of photography.
Belin gave his name to a college of
Vesoul (Haute-Saône ).References
