Операция квантования световых распределений широко применяется в задачах хранения, передачи, обработки и сжатия информации. Для определения наиболее универсального метода квантования голограмм исследованы четыре итеративных и четыре неитеративных метода квантования, а также два метода, предложенных ранее авторами настоящей статьи и основанных на неитеративном анализе гистограммы распределения интенсивности. Для перечисленных методов квантования проанализированы скорость преобразования (квантования) и качество изображений, оптически восстанавливаемых с помощью компьютерно-синтезированных голограмм. Голограммы отображались на микрозеркальном модуляторе света, изображения объектов восстанавливались в лазерном излучении. Качество восстановления оценено с помощью таких метрик качества, как индекс структурного сходства, коэффициент корреляции и спекл-контраст. Установлено, что из всех рассмотренных методов квантования качество восстановленных изображений выше при использовании гистограммных методов – на 19 % по сравнению с неитеративными методами и на 15 % по сравнению с ресурсоёмкими итеративными методами (расчёт по метрикам качества). При этом скорость квантования голограмм разработанными гистограммными методами на порядок выше скорости итеративных методов. Совместный учёт относительной интенсивности и указанных метрик качества реализован путём вычисления целевой функции. Рассчитанное значение целевой функции для гистограммных методов больше её значений для неитеративных и итеративных методов на 5 и 2 % соответственно. Полученные результаты демонстрируют преимущества гистограммных методов (высокое качество квантования в совокупности с малым временем обработки изображения) по сравнению с рассмотренными методами квантования в задаче реконструкции изображений из бинарных голограмм. Исходя из этого можно рекомендовать использовать рассмотренные гистограммные методы квантования при оптической реконструкции объёмных сцен, компрессии голографических данных, а также высокоскоростной модуляции световых полей.</p></abstract><trans-abstract xml:lang="en"><p>The problem of optical reconstruction of object images using display of quantized computer-generated holograms on a high-speed digital micromirror device is considered. The quantization of light distributions is widely used for information storage, transmission, processing and compression. To determine the most universal hologram quantization method, four iterative, four noniterative quantization methods, and two methods proposed earlier by the authors of this paper and based on noniterative analysis of the intensity distribution histogram, are investigated. The processing (quantization) rate and quality of images optically reconstructed with computer-generated holograms were analyzed for the methods. The holograms were displayed on a digital micromirror device. Object images were reconstructed in laser light. The quality of reconstruction was assessed using quality metrics such as structural similarity index, correlation coefficient and speckle contrast. It was found that the quality of reconstructed images for the histogram methods is higher by 19 % compared to non-iterative methods and by 15 % compared to resource-intensive iterative methods. The rate of hologram quantization by the developed histogram methods is an order of magnitude higher than the rate of iterative methods. Joint accounting of relative intensity and the specifi ed quality metrics is realized by calculation of the target function. The target function of histogram methods exceeds its values of non-iterative and iterative methods by 5 and 2 %, respectively. The obtained results demonstrate the advantages of the histogram methods (high quality of quantization and little time of image processing), in comparison with the other ones for image reconstruction from binary holograms. Thus the histogram quantization methods are recommended for optical reconstruction of volumetric scenes, compression of holographic data, and high-speed modulation of light fi elds.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная голография</kwd><kwd>микрозеркальный модулятор света</kwd><kwd>гистограмма интенсивности</kwd><kwd>оптические измерения</kwd><kwd>методы квантования</kwd><kwd>бинаризация</kwd><kwd>дифракционный оптический элемент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computer-generated holography</kwd><kwd>digital micromirror device</kwd><kwd>intensity distribution histogram</kwd><kwd>quantization methods</kwd><kwd>binarization</kwd><kwd>diffractive optical element</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (РНФ), грант № 22-79-10340</funding-statement><funding-statement xml:lang="en">The work was carried out with financial support by Russian Science Foundation (RSF), project no. 22-79-10340</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">He Z., Sui X., Jin G., Chu D., Cao L.
