In 1907, Belin invented a phototelegraphic apparatus called the Bélinographe, a system for sending photographs over telephone and telegraphic networks. Around this time other scientists, such as Arthur Korn, had also been developing teechnology to transmit images over long distances. Belin's invention has been used for journalistic photos since 1914.
In this apparatus, the transmitter traverses the original image point by point. At each point a measurement of light intensity[clarification needed] 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.[clarification needed]
Belin was a president of the French Company of photography.[clarification needed]
