Установлено, что при τр &lt; τg и τр = τg характерные расстояния зоны видимости не зависят от формы импульса подсветки. Для их определения можно использовать полученные ранее выражения для импульсов подсветки прямоугольной формы. При τр &gt; τg ПЭП для рассматриваемых случаев представляет собой, как правило, выпуклую асимметричную кривую с одним максимумом в точке Sмакс. Для простейших форм импульсов подсветки, моделируемых треугольниками или трапециями, получены аналитические выражения, которые позволяют вычислить значение Sмакс по известным расстоянию задержки и длительности импульса подсветки. Для соотношения τр &gt; τg предложен метод калибровочной постоянной для определения расстояния Sмакс при реальной форме импульса подсветки.</p></abstract><trans-abstract xml:lang="en"><p>Herein, the spatial-energy profiles (SEPs) of the recorded signal was numerically studied at different shapes of the illumination pulse and ratios between the durations of illumination τр and registration τg pulses at a fixed delay distance. It was established that at τр &lt; τg and τр = τg the characteristic distance of visibility ranges do not depend on the shape of the illumination pulse. For their determination it is possible to use the previously obtained expressions for illumination pulses of a rectangular shape. As a rule, for the cases considered at τр &gt; τg SEP is a convex asymmetric curve with one maximum in a point Smax. For the simplest forms of illumination pulses designed by triangles or trapezoids the analytical expressions were obtained, allowing calculation of the value Smax on the known delay distance and the duration of the illumination pulse. For the ratio τр &gt; τg, the method of the calibration constant was also proposed to determine the distance Smax at a real shape of the illumination pulse.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>активно-импульсная система видения</kwd><kwd>пространственно-энергетический профиль</kwd><kwd>расстояние задержки</kwd><kwd>характерные расстояния зоны видимости</kwd><kwd>положение максимума сигнала</kwd></kwd-group><kwd-group xml:lang="en"><kwd>active-pulse vision system</kwd><kwd>spatial-energy profile</kwd><kwd>distance of delay</kwd><kwd>characteristic distances of visibility range</kwd><kwd>position of signal maximum</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">И.
