Текстурные, яркостные и цветовые характеристики солнечных бликов несут информацию о состоянии водной среды и атмосферы. Поэтому солнечные блики играют важную роль в дистанционном зондировании морей и океанов, являясь в одних задачах полезным сигналом, а в других — шумом. Яркие полосы (подводные каустики) на дне водоёмов, вызванные волнением, также являются показателем формы (структуры) поверхности. С помощью волновой теории света изучено распределение интенсивности в окрестности каустики (т. е. там, где приближение геометрической оптики не применимо), возникающее при преломлении света на взволнованной водной поверхности. Получена формула, определяющая параметры волнения по ширине каустической зоны. Корректность метода проверена в экспериментах на бассейне. Также в работе представлен краткий обзор работ авторов, касающихся солнечных бликов и подводных каустик.</p></abstract><trans-abstract xml:lang="en"><p>The Sun glints that are observed on the water surface have different radiances, shapes, and color shades, depending on the positions of the Sun and the observer, the water surface statement, and the transparency of the water and atmosphere. The texture, radiance, and color characteristics of Sun glints carry information about the state of the water and atmosphere. Therefore, Sun glints play an important role in remote sensing of seas and oceans, being a useful signal in some problems and noise in others. Bright stripes (underwater caustics) on the bottom of the water basin that are caused by the waves are also an indicator of the water surface shape. The application of the wave theory of light is used to study the intensity distribution in the vicinity of the caustic (i. e., where the geometric-optical approximation is inapplicable), which arises when light is refracted on a wavy water surface.</p><p>A formula, which determines the parameters of the waves from the width of the caustic zone is obtained. The correctness of the method has been verified by experiments carried out in the pool. Also, here we give a brief overview of our investigations related to sun glints and underwater caustics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дистанционное зондирование</kwd><kwd>солнечные блики</kwd><kwd>зеркальные точки</kwd><kwd>радиусы кривизны</kwd><kwd>подводные каустики</kwd><kwd>обратные задачи</kwd><kwd>интегральные уравнения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>remote sensing</kwd><kwd>sun glints</kwd><kwd>specular points</kwd><kwd>radii of curvature</kwd><kwd>underwater caustics</kwd><kwd>inverse problems</kwd><kwd>integral equations</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gardashov R.G.
