Гибридный асимптотический метод анализа каустик оптических элементов в радиально-симметричном случае

Гибридный асимптотический метод анализа каустик оптических элементов в радиально-симметричном случае

Abstract

In this work we propose a new approach to calculating the distribution of light fields in the framework of geometrical optics. A new integral operator for computing the intensity distribution in the geometrical optics approximation is suggested. Using the proposed method, we derive the intensity distributions of previously studied wavefronts. Singular points of these distributions are found and the intensity distributions near the caustics are calculated. The developed method is used to calculate the formation of caustics by harmonic diffractive optical elements in the axially symmetric case.

В статье предложен новый подход к расчёту распределений световых полей в рамках геометрической оптики. Описан новый интегральный оператор для вычисления распределения интенсивности в рамках геометрической оптики. В рамках предложенного метода найдены распределения интенсивности от ранее изученных падающих пучков. Найдены особые точки этих распределений, и рассчитаны распределения интенсивности вблизи каустик. Разработанный метод применен для расчета формирования каустик гармоническими дифракционными оптическими элементами в радиально-симметричном случае.
