چند عکس از دانشمندان جهانی

[دانه کولانه]

اسمشو والا سخت بود جی بذارم وی نت عکس چند دانشمند که در زمینه نور و اپتیک
فعالیت کرده بودند دیدم در واقع برای علی جوان سرچ کردم به اینجا رسیدم


Ali Javan and his associates William Bennett Jr. and Donald Herriott at Bell Labs were first to successfully demonstrate a continuous wave (cw) helium-neon laser operation (1960-1962). (Courtesy of Bell Labs, Lucent Technologies.)

John Tyndall in 1854 demonstrated to the Royal Institution that a water jet can act as a light guide (Courtesy of AIP Emilio Segrè Visual Archives, Zeleny Collection.)

Sailors visiting Iceland during the 17th century brought back to Europe calcite crystals (Iceland spar) which had the unusual property of showing double images when objects were viewed through it. Erasmus Bartholinus described this property as the effect of double refraction and later Christiaan Huygens (1629 - 1695), a Dutch physicist, explained this double refraction in terms of ordinary and extraordinary waves. Christiaan Huygens made many contributions to optics and wrote prolifically on the subject. (Courtesy of AIP Emilo Segrè Visual Archives.)

Friedrich Carl Alwin Pockels (1865 - 1913) son of Captain Theodore Pockels and Alwine Becker, was born in Vincenza (Italy). He obtained his doctorate from Göttingen University in 1888. From 1900 until 1913, he was a professor of theoretical physics in the Faculty of Sciences and Mathematics at the University of Heidelberg where he carried out extensive studies on electro-optic properties of crystals - the Pockels effect is basis of many practical electro-optic modulators (Courtesy of the Department of Physics and Astronomy, University of Heidelberg, Germany.)
