В эксперименте интенсивность света настолько низка, что скорость детектирования фотонов матрицей становится сравнимой со скоростью ее темновых отсчетов. Для минимизации влияния темновых отсчетов на фантомное изображение (ФИ) и уменьшения флуктуаций в спекл-структуре изображения измеряемые данные подвергаются покадровой фильтрации по количеству детектированных отсчетов на кадр, а ФИ сглаживается с помощью процедуры скользящего близкодействующего среднего. Оптимальная настройка режима фильтрации приводит к значительному сокращению времени сбора данных (вплоть до нескольких секунд), необходимого для получения высококачественного ФИ.</p></abstract><trans-abstract xml:lang="en"><p>   Here we present an experiment on ghost imaging with a pseudo-thermal light source and a single-photon detector array. In the experiment, the light intensity is taken to be so low that the photon detection rate is comparable to the dark counts rate. To minimize the influence of dark counts on the ghost image (GI) and reduce fluctuations in the speckle pattern of the image, the measured data is filtered frame by frame by the number of detected counts per frame, and the GI is smoothed using a moving short-range averaging. We have found that optimizing the filtering procedure leads to a significant reduction in the data acquisition time (down to several seconds) required for obtaining a high-quality GI.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фантомная визуализация</kwd><kwd>псевдотепловой свет</kwd><kwd>слабые потоки</kwd><kwd>матрица однофотонных детекторов</kwd><kwd>темновые отсчеты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ghost imaging</kwd><kwd>pseudo-thermal light</kwd><kwd>weak illumination</kwd><kwd>single-photon detector array</kwd><kwd>dark counts</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">С.Я.К. благодарит за финансовую поддержку Белорусский республиканский фонд фундаментальных исследований (проект № Ф25UZB-035)</funding-statement><funding-statement xml:lang="en">S.Ya.K. thanks the Belarusian Republican Foundation for Basic Research for financial support (project No. F25UZB-035)</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">M.
