Одним из основных недостатков данной методики является сравнительно низкая скорость работы, что ограничивает ее применимость при работе с быстро протекающими процессами или движущимися объектами. Предложена модификация техники вычислительной фантомной визуализации, позволяющая снять это ограничение. Продемонстрировано, что спектральное мультиплексирование спекл-структур дает возможность ускорить процесс восстановления изображения. Например, при увеличении числа спектральных каналов с 4 до 10, происходит увеличение отношения сигнал-шум в шесть раз. В то же время использование классической монохромной фантомной визуализации не позволяет восстановить изображение в тех же условиях и с тем же количеством измерений. Предложенная методика привлекательна для таких требовательных к быстродействию приложений, как передача данных и дистанционное зондирование.</p></abstract><trans-abstract xml:lang="en"><p>The ghost imaging technique allows us to recover information about an object in conditions of noisy transmission channels, commensurate with the intensity of the speckle structures involved in the reconstruction. One of the main disadvantages of this technique is relatively slow reconstruction speed. This limits its applicability for study of dynamic processes or fast-moving objects. In this paper, we propose a modification of the computational ghost imaging technique that allows us to overcome this limitation. It is shown that the spectral multiplexing of the speckle patterns speeds up the image reconstruction. Increase in the number of spectral channels from 4 to 10 leads to the increase of the signal-to-noise ratio by the factor of 6. Simultaneously, under the same conditions and with the same number of measurements classical monochrome ghost imaging does not reconstruct the picture at all. This makes the proposed technique attractive for high-speed demanding applications such as communications and remote sensing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фантомная визуализация</kwd><kwd>спектральный суперконтинуум</kwd><kwd>пространственный модулятор света</kwd><kwd>передача информации</kwd><kwd>дистанционное зондирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ghost imaging</kwd><kwd>supercontinuum</kwd><kwd>spatial light modulator</kwd><kwd>data transmission</kwd><kwd>remote sensing</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной финансовой поддержке Минобрнауки РФ в рамках Государственного задания (Паспорт № 2019-0903) и Физико-технического мегафакультета Университета ИТМО в рамках гранта НИРМА.</funding-statement><funding-statement xml:lang="en">The study was partially funded by the Ministry of Education and Science of the Russian Federation (Passport No. 2019-0903) and RPMA grant of School of Physics and Engineering of ITMO University.</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">Willner A.E., Zhao Z., Liu C., Zhang R., Song H., Pang K., Manukyan K., Song H., Su X., Xie G., Ren Y., Yan Y., Tur M., Molisch A.F., Boyd R.W., Zhou H., Hu N., Minoofar A., Huang H.
