摘要

摘要在准光学近似的框架内研究了在真空或线性各向同性介质中传播方向相近的三个平面单色波干涉产生的极化奇异现象。在波的线性偏振的特殊选择下，确定了偏振为线性时在横截面上形成 L 线和偏振为圆形时形成 C 点的条件，并得到了这种偏振奇点位置的解析表达式。

Polarization Singularities in the Interference of Three Plane Waves

Abstract

Polarization singularities arising from the interference of three plane monochromatic waves with close propagation directions in a vacuum or a linear isotropic medium are studied within the framework of the quasi-optical approximation. With a special choice of linear polarization of waves, the conditions for the formation of L-lines in the cross section, where the polarization is linear, and C-points, where the polarization is circular, are determined, and analytical expressions are obtained for the location of such polarization singularities.

期刊介绍： Optics and Spectroscopy (Optika i spektroskopiya), founded in 1956, presents original and review papers in various fields of modern optics and spectroscopy in the entire wavelength range from radio waves to X-rays. Topics covered include problems of theoretical and experimental spectroscopy of atoms, molecules, and condensed state, lasers and the interaction of laser radiation with matter, physical and geometrical optics, holography, and physical principles of optical instrument making.
