Приведены результаты измерений индикатрис диффузно-рассеянного излучения от рабочих поверхностей фотодиодов Hamamatsu S6337, S1337. Построена приближенная модель распространения излучения в трап-детекторе, учитывающая реальную форму индикатрис рассеяния. Изучены влияние количества актов диффузного рассеяния излучения и числа его отражений на точность расчета рассматриваемых потерь и их зависимость от поляризации падающего лазерного излучения.</p></abstract><trans-abstract xml:lang="en"><p>The losses in the trap detector due to absorption of diffusely scattered laser radiation on its walls are analyzed. The measurements results for the indicatrix of this radiation from the working surface of photodiodes Hamamatsu S6337 and S1337 are given. The approximate model of distribution of radiation in the trap detector, which takes into account the real profile of the indicatrix of scattering is constructed. The effect of acts of the diffuse scattering quantity and of the number of scattering reflections on the accuracy of the considered losses calculation is analyzed. The influence of polarization of the incident laser radiation on these losses value is investigated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерное излучение</kwd><kwd>трап-детектор</kwd><kwd>диффузное рассеяние</kwd><kwd>laser emission</kwd><kwd>trap detector</kwd><kwd>diffuse scattering</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">Fox N.
