Данный способ является альтернативным методом динамического формирования распределения интенсивности лазерного пятна. Построена математическая модель расчета распределения интенсивности осциллирующего луча и температурных полей, индуцированных лазерным воздействием. Разработан алгоритм оптимизации параметров высокочастотных колебаний луча на основе решения обратной задачи теплопроводности для получения равномерного нагрева приповерхностного слоя материала.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, a method has been developed for heat treatment of objects with a complex surface profile with a rapidly oscillating laser beam with modulated radiation power. This method is an alternative method for the dynamic formation of the distribution of the intensity of the laser spot. A mathematical model for calculating the distribution of the intensity of the oscillating beam and temperature fields induced by laser treatment is created. An algorithm for optimizing the parameters of high-frequency oscillations of the beam based on the solution of the inverse problem of thermal conductivity to obtain uniform heating of the nearsurface layer of the material is developed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерная закалка</kwd><kwd>теплопроводность</kwd><kwd>компьютерное моделирование</kwd><kwd>обратная задача теплопроводности</kwd><kwd>сканатор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laser hardening</kwd><kwd>heat transfer</kwd><kwd>computer modeling</kwd><kwd>inverse heat transfer problem</kwd><kwd>scanner</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">&lt;em&gt;Pantelis D.
