Также модуляторы используются при создании дифракционных нейроподобных систем. Востребованность модуляторов данного типа обусловлена уникальным для оптических систем сочетанием высокой скорости переключения и большого пространственного разрешения. В настоящей работе представлены результаты экспериментального исследования микрозеркального пространственно-временно́ го модулятора света HDSLM54D67 (UPO Labs, Китай) с передовыми для своего класса характеристиками по заявлениям производителя. Оценены реальные значения пространственных и скоростных параметров указанного модулятора при отображении бинарных компьютерносинтезированных голограмм Фурье и двумерных распределений в виде графических примитивов. Выявлена аномальная модуляция левой половины матрицы микрозеркал, приводящая к паразитному двоению восстановленных из голограмм изображений. Проанализированы причины возникновения данных искажений, выявлена их связь с особенностями устройства управляющего блока модулятора. Определены ограничения применимости данной модели микрозеркального модулятора в соответствии с выявленными пространственными ограничениями (использование только половины матрицы микрозеркал с разрешением 1358×1600 пикселов) и сформулированы предложения по оптимальной интеграциимодулятора в оптическую систему. Применение модулятора возможно, однако пропускная способность будет в два раза меньше теоретически максимальной. Результаты исследования можно использовать в дальнейших оптических экспериментах с данным модулятором света, в том числе и для задачи построения дифракционной нейронной сети.</p></abstract><trans-abstract xml:lang="en"><p>Digital micromirror devices are widely used for optical processing of graphic information, including for the purpose of building holographic display systems and adaptive formation of light beams. Modulators are also used in the creation of diffraction neuron-like systems. The demand for modulators of this type is due to the unique combination of high switching speed and high spatial resolution for optical systems. This paper presents the results of an experimental study of the HDSLM54D67 digital micromirror device (UPO Labs, China), which, according to the manufacturer, has advanced characteristics for its type. The true values of its spatial and velocity parameters are estimated by displaying binary computer-synthesized Fourier holograms and two-dimensional distributions in the form of geometric primitives. The results revealed an abnormal modulation of the left half of the micromirror matrix, leading to a parasitic doubling of the images reconstructed from the holograms. The analysis of the causes of these distortions was carried out, and their connection with the features of the modulator control unit was revealed. The limitations of the applicability of this digital micromirror device model are determined in accordance with the identifi ed spatial limitations (using only the half of the micromirror matrix with a resolution of 1358×1600 pixels) and proposals for optimal integration of the modulator into an optical system are formulated. The use of a modulator is possible, but theoretically the maximum bandwidth will be reduced by 2 times. The results of the study can be used in further optical experiments with this digital micromirror device, including for the task of constructing a diffraction neural network.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная голография</kwd><kwd>микрозеркальный модулятор света</kwd><kwd>дифракционные оптические нейронные сети</kwd><kwd>дифракционный оптический элемент</kwd><kwd>когерентный оптический дифракционный процессор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computer-generated holography</kwd><kwd>digital micromirror device</kwd><kwd>diffractive optical neural networks</kwd><kwd>diffractive optical element</kwd><kwd>coherent optical diffraction processor</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (РНФ), грант № 23-12-00336.</funding-statement><funding-statement xml:lang="en">The work was carried out with fi nancial support by Russian Science Foundation (RSF), project no. 23-12-00336.</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">Lecun Y., Bottou L., Bengio Y., Haffner P.
