Maurice Leblanc (engineer)

Maurice Leblanc ( born March 2, 1857 in Paris, † October 27, 1923 ) was a French electrical engineer.

After his electrical engineering training at the École Polytechnique in Paris, he worked briefly for the railroad.

Thereafter he was mainly concerned with the improvement of electric motors and generators. He invented an improved vacuum pump and also worked in the field of cooling.

From 1875 he studied the inertia of the human eye in fast scans to transmit color images electrically.

On 1 December 1880 he published the article Etude sur la transmission électrique of impressions lumineuses électrique in the La Lumiere, where he performed the five basic functions of your TV system:

• A converter for converting light into electricity
• A scanner to decompose the image into its components
• A method for synchronization of transmitter and receiver
• Means reconvert the electrical signals into light
• A screen to view the image

The scanning system he wanted to realize with a prism for splitting the light into the seven colors of the spectrum, mirrors and slit diaphragms. A selenium cell each spectral color should then drive a relay.

1903-09 he was professor of electrical engineering at the Ecole des Mines.
