Для повышения качества кодирования видеопотоков и обеспечения высокой пропускной способности системы кодирования экспериментально реализовано голографическое кодирование в пространственно-некогерентном излучении цветного видеопотока формата 4К с цифровым вводом информации и динамически сменяющимися кодирующими элементами-голограммами. Для ввода кодируемой видеоинформации и отображения голограмм использованы жидкокристаллические пространственно-временны́ е модуляторы света высокого разрешения. Метод кодирования основан на регистрации оптической свёртки изображения входной сцены с кодирующим откликом голограммы. При этом поочерёдно кодируются отдельные цветовые каналы каждого кадра видеопотока. Для декодирования использованы численные методы инверсной фильтрации и регуляризация. Результаты работы будут полезны при создании систем защищённой видеосвязи высокого разрешения нового поколения.</p></abstract><trans-abstract xml:lang="en"><p>The communications number and information size are significantly increasing. Transmission of various types information (including video information) should be fast and protected from unauthorized access. The use of optical encryption for this purpose makes it possible to encode large data arrays with high cryptographic strength. Most optical information encoding systems use coherent light, which results in an extremely low signal-to-noise ratio in decrypted images. Holographic encryption of color 4K video with digital information input and dynamically changeable encoding holograms by means of the liquid crystal spatial light modulators of high resolution was implemented for the first time. The method is based on optical convolution of the input image with the encoding hologram using spatially-incoherent light. Color encoding is carried out by sequential encryption of different color channels of each video frame. Decryption is carried out by numerical methods of inverse filtering with regularization. Results of this work can be used for creation of high resolution secure video communication systems of new generation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптическое кодирование</kwd><kwd>цифровая голография</kwd><kwd>киноформ</kwd><kwd>жидкокристаллические пространственно- временные модуляторы света</kwd><kwd>регистрация изображений</kwd><kwd>оптическая обработка информации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optical encryption</kwd><kwd>digital holography</kwd><kwd>kinoform</kwd><kwd>liquid crystal spatial light modulator</kwd><kwd>image registration</kwd><kwd>optical information processing</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена при финансовой поддержке Российского научного фонда, грант № 21-79-00117.</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">Alfalou A., Brosseau C.
