He is the inventor in 1907 of a phototelegraphic apparatus called the Bélinographe, a system able to send remote photographs, 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
Radio waves
Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers. Like all other electromagnetic waves,...

.

In this apparatus, the transmitter traverses the original image point by point, and measures the light intensity via an electric eye
Electric eye
An electric eye is a photodetector used for detecting obstruction of a light beam. An example is the door safety system used on garage door openers that use a light transmitter and receiver at the bottom of the door to prevent closing if there is any obstruction in the way that breaks the light...

. 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 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.

Belin was a president of the French Company of photography.
