Scattering, английский
- Утруска
- Intrinsic fiber losses caused by undissolved particles, boundary roughness, and intrinsic material losses
- Loss of light that is scattered off atoms in different directions, so it escapes from the fiber core. a major component of fiber attenuation.
- Рассеяние. процесс, в ходе которого происходит изменение направления или энергии падающей частицы или радиации, вызываемое столкновением с другой частицей или системой частиц (мос, 5). рассеяние ми — рассеяние электромагнитного излучения сферическими частицами при отсутствии четкой зависимости между размером частиц и длиной волны излучения. оно имеет большое значение для исследований по загрязнению атмосферного воздуха. свет интенсивно рассеивается частицами диаметром около 0,1—1 мкм; происходящее при этом снижение видимости является функцией квадрата радиуса частиц. рассеяние рэлея — рассеяние частицами, радиус которых меньше ую длины волны излучения (например, рассеяние света молекулами кислорода и азота в воздухе).
