Предлагаются схемы лидаров для дистанционного измерения ЧКХ и алгоритмы определения оптических характеристик воды по измеренной ЧКХ. Обсуждаются принципы построения лазерной системы наблюдения морского дна, которая контролирует влияние водной среды на формируемое ею изображение и обеспечивает возможность коррекции искажений изображения, обусловленных рассеянием света в воде.</p></abstract><trans-abstract xml:lang="en"><p>We develop algorithms for retrieval of the water layer modulation transfer function (MTF) from the radiance of backscattered laser pulse. A lidar diagram is developed for remote measuring of the MTF. The water optical properties are then retrieved from measured MTF. We also propose a laser imaging system for sea bottom observation which corrects image distortion caused by light scattering in the water.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лидар</kwd><kwd>видение</kwd><kwd>вода</kwd><kwd>частотно-контрастная характеристика</kwd><kwd>коррекция изображений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lidar</kwd><kwd>imaging</kwd><kwd>water</kwd><kwd>modulation transfer function</kwd><kwd>image correction</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">Браво-Животовский Д.М., Гордеев Л.Б., Долин Л.С., Моченев С.Б.
