Распределение интенсивности в окрестности точки фокуса частично поляризованной высокоапертурной оптической системы

Abstract

The paper presents the mathematical technique for calculation of three dimensional intensity distribution near a focal point of a high aperture optical system in case of quasi monochromatic partly polarized light. It is based on Huygens-Fresnel principle: spherical wave at an exit pupil is considered as a numerous set of elementary secondary partly polarized light sources. The total intensity is calculated as superposition of complex wave amplitudes taking into account polarization orientation, complex degree of polarization, orientation of detector aperture and coherence length of quasi-monochromatic light.
