The Bélinographe was a system that was capable of sending photographs to remote locations through telegraph and telephone networks. In 1921 the process was improved so that it could be sent via radio waves as well.
With the Bélinographe, the device uses an electric eye to measure the light intensity.
The intensity levels are transmitted to a receiver, where a source of light is able to reproduce the intensities that were measured by the transmitter, impressing on photographic paper.
