Lorsque l'intensit\u00e9 lumineuse descend en dessous d'un certain seuil, la vision est fortement r\u00e9duite. C'est l\u00e0 qu'interviennent les syst\u00e8mes de vision nocturne, qui amplifient la lumi\u00e8re faible ou d\u00e9tectent les signatures thermiques.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les appareils de vision nocturne fonctionnent soit en captant <strong>lumi\u00e8re infrarouge<\/strong> (qui est invisible \u00e0 l'\u0153il nu) ou en utilisant toute source de lumi\u00e8re disponible, comme celle de la Lune ou des \u00e9toiles, <strong>plus lumineux<\/strong>. Cela vous permet d'y voir plus clair dans <strong>sombre<\/strong> ou <strong>faible<\/strong> les environnements o\u00f9 la luminosit\u00e9 est insuffisante.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-night-vision-process\"><strong>Proc\u00e9d\u00e9 de vision nocturne.<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ce nouveau gadget militaire permet de rendre visibles les sc\u00e8nes sombres en amplifiant les infimes quantit\u00e9s de lumi\u00e8re provenant de la lune, des \u00e9toiles ou d'autres sources. Il d\u00e9tecte les photons faibles qui rebondissent sur les objets, les transforme en \u00e9lectrons, puis les amplifie \u00e0 l'aide d'une plaque de verre sp\u00e9ciale. Ces \u00e9lectrons viennent ensuite frapper un \u00e9cran recouvert de phosphore pour former une image.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les appareils plus anciens utilisent un phosphore vert, ce qui donne une image verte en vision nocturne. Mais la toute derni\u00e8re technologie d'Elbit utilise un phosphore blanc, ce qui permet d'obtenir des images en noir et blanc offrant un meilleur contraste et une meilleure nettet\u00e9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La vision nocturne repose sur les principes suivants : <strong>amplification de la lumi\u00e8re et d\u00e9tection thermique<\/strong>. Il est important de comprendre deux concepts fondamentaux de la physique qui permettent \u00e0 la vision nocturne de fonctionner efficacement :<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-night-vision-vs-thermal-imaging\">Vision nocturne ou imagerie thermique ?.<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">On confond souvent la vision nocturne et l'imagerie thermique, mais il s'agit de technologies distinctes.
