Показано, что в зависимости от мощности лазерного УФ-пучка возможно существование двух различных статичных локализованных хиральных структур размером порядка 25 и 10 мкм. Показаны процессы реконфигурации локализованных хиральных жидкокристаллических структур друг в друга и в полностью фрустрированное состояние пленки хирального нематического жидкого кристалла. Эти локализованные структуры могут применяться в качестве миниатюризированных перестраиваемых оптических элементов для фокусировки и структурирования проходящих световых пучков.  </p></abstract><trans-abstract xml:lang="en"><p>A method for creating an optical scheme and the principle of using photoactive samples of chiral nematic liquid crystals for optical molecular generation of localized chiral structures are considered. It is shown that the existence of two different static localized chiral structures with sizes of about 25 and 10 µm is possible, depending on the power of the UV laser beam. The processes of reconfiguration of localized chiral liquid crystal structures into each other and into a completely frustrated state of a chiral nematic liquid crystal film are described. These localized structures can be used as miniaturized tunable optical elements for focusing and structuring transmitted light beams. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>нематический жидкий кристалл</kwd><kwd>светопоглощающая хиральная молекулярная добавка</kwd><kwd>оптическая схема</kwd><kwd>статичная локализованная хиральная структура</kwd><kwd>перестройка поля директора</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nematic liquid crystal</kwd><kwd>light-absorbing chiral molecular additive</kwd><kwd>optical scheme</kwd><kwd>static localized chiral  structure</kwd><kwd>director field restructuring</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">авторы благодарят Prof. Etienne Brasselet (University of Bordeaux, France), Dr. Supitchaya Iamsaard, Dr. Federico Lancia и Prof. Nathalie Katsonis (Stratingh Institute for Chemistry, University of Groningen, The Netherlands) за приготовление смесей фотоактивных хиральных нематических жидких кристаллов и предоставленные жидкокристаллические образцы.</funding-statement><funding-statement xml:lang="en">The authors thank Prof. Etienne Brasselet (University of Bordeaux, France), Dr. Supitchaya Iamsaard, Dr. Federico Lancia and Prof. Nathalie Katsonis (Stratingh Institute for Chemistry, University of Groningen, The Netherlands) for preparation of photoactive chiral nematic liquid crystal mixtures and provided liquid crystal samples.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hamdi R. et al.
