摘要： Изобретение относится к области оптофлюидики, адаптивной оптики и оптоэлектроники и может быть использовано для создания адаптивных оптических систем, способных менять знак фокусного расстояния и перестраивать оптические характеристики без использования системы подвижных линз. Предлагаемая варифокальная жидкая линза отличается простотой конструкции и способа управления фокусным расстоянием, а также широким диапазоном перестройки фокусного расстояния и возможностью изменения знака фокусного расстояния. Суть изобретения в том, что на прозрачную поверхность наносится капля нелетучей жидкости с добавлением поглощающего пучок лазера красителя, формирующая отличный от нуля краевой угол смачивания, а изменение ее фокусного расстояния, происходит вследствие деформации ее свободной поверхности, под действием центробежных термокапиллярных сил, генерируемых тепловым воздействием лазерного пучка, при этом величина и знак фокусного расстояния определяются мощностью пучка. Преимущества предлагаемой варифокальной жидкой линзы в том, что в качестве жидкости может быть использована любая нелетучая жидкость, не требуется изготовление герметичной ячейки или ячейки сложной конструкции; перестройка фокусного расстояния осуществляется бесконтактно с помощью лазерного пучка или сфокусированного излучения любого другого источника света, например, фотодиода, ртутной или галогеновой лампы, достаточно лишь чтобы излучение поглощалось либо в объеме капли, либо материалом подложки.
