A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now creat ...
over telephone wires via telegraphic networks.
Belin's invention had been used for journalistic photos since 1914, and the process was improved by 1921 to enable transmission of images by radio waves
Radio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz ( GHz) and below. At 300 GHz, the corresponding wavelength is 1 mm (s ...

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

Bélinographe
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. Other scientists such asArthur Korn
Arthur Korn (20 May 1870 – 21 December/22 December 1945) was a German physicist, mathematician and inventor. He was involved in the development of the fax machine, specifically the transmission of photographs or telephotography, known as the B ...

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.
