Параметры призменного дефлектора связаны с характеристиками лазерного излучения, параметрами сканируемой области и положением дефлектора, а также ограничены различными факторами, например, требованиями безопасности или временем сканирования. Целью работы являлся анализ взаимосвязи параметров сканирующей системы (таких как угол подачи излучения на грань призменного дефлектора, диаметр лазерного пучка) с конструктивными параметрами её сканирующего элемента – призменного дефлектора.</p><p>Рассмотрен вариант расчёта частоты следования лазерных импульсов через количество лазерных пятен и их коэффициент перекрытия. Предложен метод расчёта характеристик призменного дефлектора, исходя из внешних параметров, таких как угол подачи излучения на грань и ширины гауссова пучка на выходе из оптической системы с размерами, безопасными для человеческого глаза. Приведены параметры призменных дефлекторов в зависимости от числа отражающих граней. Показана зависимость размера дефлектора от угла подачи излучения на отражающую грань.</p><p>При проектировании призменного дефлектора лазерного сканера, предназначенного для заполнения некоторой области сканирования с требуемым угловым размером σ, варьируя такие параметры как количество граней m и угол подачи α, можно добиться оптимальных для поставленной задачи характеристик дефлектора и режима сканирования.</p></abstract><trans-abstract xml:lang="en"><p>The prism deflector which is a multifaceted prism with reflective facets is the most common scanning element that allows to quickly fill a wide scanning area with laser radiation pulses along one coordinate. The parameters of a prismatic deflector are related to the characteristics of the laser radiation of the scanned area parameters and of the deflector position, and are also limited by various factors, such as safety requirements or scanning time. The aim of this work was to analyze the relationship between the external operating conditions of a laser scanning system and the internal design parameters of a prism deflector.</p><p>A variant of calculating of laser pulses frequency by the number of spots and their overlap coefficient is considered. A method for calculating of a prism deflector characteristics based on external parameters, such as the angle of incidence of radiation to the facet and the width of the Gaussian beam with dimensions that are safe for а human eye is proposed. Рrismatic deflectors parameters are proposed depending on the number of reflecting facets. Dependence of a deflector size on the angle of radiation incidence to the reflecting face is shown.</p><p>When designing a prismatic deflector of a laser scanner used to fill a certain scanning area with the required angular size σ by varying such parameters as the number of faces m and the feed angle α it is possible to achieve optimal deflector characteristics and scanning mode for the task.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерное сканирование</kwd><kwd>сканер</kwd><kwd>призменный дефлектор</kwd><kwd>сканирующая система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laser scanning</kwd><kwd>scanner</kwd><kwd>prismatic deflector</kwd><kwd>scanning system</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">Низаметдинов Н.Ф.
