Приведены результаты исследования возможности передачи голографической информации по радиоканалу Wi-Fi 40 МГц. Показано, что использование для этого двух основных модальностей 3D-изображения — карты глубин голографируемого объекта и текстуры его поверхности достаточно для синтезирования на приемном конце канала связи полноценной голограммы, восстанавливающей объект голографирования с непрерывным вертикальным и горизонтальным параллаксами.Метод. Метод передачи 3D-голографической информации подобен известному в радиотехнике методу передачи информации на одной боковой полосе (Single-sideband modulation, SSB). Существенное отличие предложенного метода состоит в том, что пространственные частоты, образующие голограмму, являются результатом одновременной амплитудной и фазовой модуляции опорного сигнала. Это затрудняет их теоретический анализ. Экспериментальное подтверждение возможности такой передачи выполнено с использованием свободного FTP-клиента с открытым исходным кодом FileZilla. Применен протокол связи для передачи информации по беспроводному каналу Wi–Fi.Основные результаты. Показано, что передаваемый информационный поток достаточен для синтеза на приемном конце канала связи голограммы, восстанавливающей 3D-изображения. При этом голографическое изображение динамически меняющегося объекта с телевизионной частотой кадровой развертки имеет непрерывный горизонтальный и вертикальный параллаксы, а пространственное разрешение восстановленного изображения не хуже телевизионного изображения стандарта высокой четкости Full HD.Практическая значимость. Экспериментально подтверждена возможность передачи по радиоканалу всей необходимой информации для воспроизведения на приемном конце канала голографического 3D-видеопотока с разрешением не ниже, чем в стандартах телевидения высокой четкости с непрерывным параллаксом.</p></abstract><trans-abstract xml:lang="en"><p>The results of the research on the possibility of transmitting holographic information over the Wi-Fi 40 MHz radio channel are presented. It is shown that the use of two main 3D image modalities for this, — a depth map of the holographic object and the texture of its surface, is sufficient to synthesize a full-fledged hologram at the receiving end of the communication channel, restoring the holographic object with continuous vertical and horizontal parallax. The method of transmitting 3D holographic information is similar to the well–known in radio engineering method of transmitting information on one sideband (Single-sideband modulation, SSB). The essential difference of the proposed method is that the spatial frequencies forming the hologram are the result of simultaneous amplitude and phase modulation of the reference signal. This complicates their theoretical analysis. Experimental confirmation of the possibility of such a transfer was performed using a free FTP client with open source FileZilla. A communication protocol has been applied to transmit information over a wireless Wi-Fi channel. It is shown that the transmitted information stream is sufficient to synthesize a hologram reconstructing 3D images at the receiving end of the communication channel. At the same time, the holographic image of a dynamically changing object with a television frame rate has continuous horizontal and vertical parallax, and the spatial resolution of the restored image was no worse than a highdefinition television image of Full HD. The possibility of transmitting all the necessary information over the radio channel to reproduce a holographic 3D video stream at the receiving end of the channel with a resolution not lower than in high-definition television standards with continuous parallax has been experimentally confirmed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>голография</kwd><kwd>голографическая информация</kwd><kwd>метод SSB</kwd></kwd-group><kwd-group xml:lang="en"><kwd>holography</kwd><kwd>holographic information</kwd><kwd>SSB method</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">Денисюк Ю.Н.
