Jules-Antoine Lissajous , born the in Versailles and died the in Plombières-lès-Dijon [ first ] , is a French physicist.

On the facade of his native house, rue Montbauron in Versailles, is affixed a souvenir plate indicating:

“In this house was born Jules Antoine Lissajous, physicist, who made the sound visible.”

Jules Lissajous is a student at Hoche high school (Versailles). He was admitted to the normal school in 1841. He obtained the aggregation of physics in 1847, classified 3 It is Of the 4 candidates [ first ] . In 1850 he supported a doctoral thesis entitled On the position of the nodes in the blades that vibrate transversely [ 2 ] .

Teacher, he is notably appointed in preparatory classes to the grandes écoles at the Saint-Louis high school.

Lissajous is known for her work on the air. He studied acoustic vibrations by reflection of luminous signals on a mirror previously fixed to the object in vibration.

He flies with a colleague physicist, Jules Maurat, in a mounted balloon, The Battle of Paris , the , in order to set up an optical communication system with the besieged.

He is elected the at the Academy of Sciences, Belles-Lettres et Arts de Savoie, with the academic title Corresponding [ 3 ] .

A method used in electronics bears his name. It makes it possible to calculate the temporal phase shift between two sinusoidal signals by studying the ellipse which they form in the X-Y mode of an oscilloscope.
