Édouard Belin (Vesoul, Haute-Saône, France, 5 March 1876 – 4 March 1963 in Territet, Canton of Vaud, Switzerland) was a French photographer and inventor, best known for inventing the Bélinographe.

Biography

In 1907, Belin invented a phototelegraphic apparatus called the Bélinographe, a system for sending photographs over telephone and telegraphic networks.[1] Around this time other scientists, such as Arthur Korn, had also been developing technology to transmit images over long distances.[2] Belin's invention has been used for journalistic photos since 1914.

The process was improved in 1921 to enable to transmission of images by radio waves.[3]

In this apparatus, the transmitter traverses the original image point by point. At each point a measurement of light intensity is made with an electric eye. The measurement is conveyed to the receiver. There, a variable intensity light source reproduces the light measured by the electric eye, while carrying out same displacements exactly. By doing this, it exposes the photographic paper and makes it possible to obtain a copy of the original image.

Modern telecopiers and photocopiers 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.

From 1926, Edoaurd Belin worked on an television apparatus. In 1926, with Holweg, he tested, using a mirror drum, the capacity for the eye to perceive pictures proposed at a very high speed.[4]

Belin was a president of the French Company of photography.

Belin gave his name to a high school of Vesoul, Haute-Saône, France.[5]
