La gloire des Fresnel S'il n'y avait qu'un nom propre associé à l'histoire des phares de France, ce serait sans doute celui de Fresnel, Augustin Fresnel, savant et ingénieur des ponts et chaussées mort en 1827 à l'âge de 39 ans. Il est l'inventeur des appareils lenticulaires qui, au début du XIXe siècle, révolutionnèrent les techniques employées pour l'éclairage des feux. L'origine des phares modernes s'est en effet condensée sur les objets dont on lui attribue la paternité, des lentilles de verre conservées comme de pieuses reliques par plusieurs institutions scientifiques. Mais la célébration dd'Augustin fait oublier le rôle joué par un autre Fresnel. Dans le Calvados, sur la plaque dédiée par souscription publique aux hommes célèbres du village de Mathieu, les noms de trois Fresnel apparaissent : ceux d'Augustin, de Fulgence, l'orientaliste, et de Léonor, l'ingénieur. Ce dernier, beaucoup moins connu que son frère, a pourtant joué un rôle décisif dans la politique de signalisation maritime de la France.

Augustin Jean Fresnel Fresnel führte zahlreiche Experimente zur Interferenz des Lichtes durch und wies als erster nach, dass zwei in verschiedenen Ebenen polarisierte Lichtstrahlen keine Interferenzeffekte zeigen. Aus diesem Experiment leitete er ab, dass die Wellenbewegung des Lichtes transversal (quer zu einer Bestimmungslinie verlaufend) und nicht - wie man bis dahin glaubte - longitudinal ist, d. h. in der Längsrichtung wie Schallwellen verlaufen. Fresnel erzeugte als erster zirkular polarisiertes Licht. Er arbeitete auch mehrere grundlegende optische Formeln aus, darunter die für Reflexion, Brechung, Doppelbrechung und für die Polarisation des Lichtes, wenn es von einem durchsichtigen Stoff reflektiert wird. Fresnels Arbeit über optische Effekte, die durch die Bewegung von Gegenständen hervorgerufen werden, war später für die Entwicklung der Relativitätstheorie von Bedeutung. Auf dem Gebiet der angewandten Optik entwarf Fresnel einen Linsentyp für Sammellinsen mit großem Öffnungsverhältnis, den man oft auch Fresnel-Linse nennt. Sie wird zur Erzeugung paralleler Lichtstrahlen in Leuchttürmen und bei Scheinwerfern verwendet, die man häufig zur Bühnenbeleuchtung einsetzt. Fresnels wissenschaftliche Arbeit war während seines Lebens nur einer kleinen Gruppe von Wissenschaftlern bekannt. Einige seiner Artikel wurden erst lange nach seinem Tode veröffentlicht. Er war Mitglied der französischen Académie des sciences und der Royal Society von London.

Visit the Molecular Expressions Website Galleria Photo Gallery ... Home Augustin-Jean Fresnel Augustin-Jean Fresnel was a nineteenth century French physicist, most often remembered for the invention of unique compound lenses designed to produce parallel beams of light, which are still used widely in lighthouses. Born in Broglie, France on May 10, 1788, Fresnel was the son of an architect and received a strict, religious upbringing. His parents were Jansenists, a sect of Roman Catholics that believed only a small, predestined group would receive salvation and that the multitudes could not change their fate through their actions on Earth. Fresnel's early education was provided by his parents and he was considered a slow learner, barely able to read by the age of 8. When he was 12-years-old, however, Fresnel began formal studies at the Central School in Caen, where he was introduced to the wonders of science and demonstrated an aptitude in mathematics. Fresnel's academic predilections inspired him to pursue a career in engineering. He entered the Polytechnic School in Paris in 1804 and, two years later, the School of Civil Engineering. Following graduation, he worked on engineering projects for several years in a variety of French government departments, but temporarily lost his post when Napoleon returned from Elba in 1815. Having already begun performing scientific work in his spare time, the change of events provided Fresnel with the opportunity to increase his efforts in this arena, and he soon began to focus on optics. Even when he was provided with a new engineering position in Paris after the second restoration, Fresnel continued his scientific investigations.

Power System How do solar panels supply energy for spacecraft? Who was Augustin Jean Fresnel? Augustin Jean Fresnel was a French physicist who lived from 1788 to 1827. He studied light and optics. Fresnel's brilliant work led him to work on lighthouses and other technical areas that needed strong, focused lights. He was famous enough to have a street named after him in Metz, France. The basic design for the Fresnel lens is still in use today, from lighthouses to stage spotlights to the solar panels on spacecrafts. How do solar concentrators work?
