Проведен анализ импульсного сигнала подсветки микродисплеев отражательного типа. Осуществлено моделирование и анализ мерцаний бинарного импульсно-кодового модулированного сигнала. Выданы рекомендации для сведения видимых мерцаний до минимального уровня.</p></abstract><trans-abstract xml:lang="en"><p>The effect of pulsed LED light sources, widely used for illumination in projection optical indicator systems on perception of human vision, is analyzed. An analysis of the impulse signal of reflectors illumination has been carried out. Modeling and analysis of flickerings of a binary pulse-code modulated signal has been performed. Recommendations for reducing of visible flickering of the LED backlight up to the minimum level have been given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>проекционная система индикации</kwd><kwd>светодиодная подсветка</kwd><kwd>бинарная импульсно-кодовая модуляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>projection display system</kwd><kwd>LED lights</kwd><kwd>binary-coded pulse modulation</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">Смирнов А.Г., Мохаммед А.С.
