Abstract

The theoretical analysis and experimental results of this report illustrate the possibility of describing of diffraction phenomena using the objects and methods, which were developed in singular optics. The aperture-diffracted field can be represented as superposition of real physically existing waves: an ordinary wave component with an amplitude half that of the incident wave, and a wave component possessing a singularity. The investigation of the singular wave component as informative part of diffraction field is an important new trend. It was shown that a system of hidden dislocation lines composes the skeleton and represents the diffraction field topology. The analysis of topology of the diffraction field in case of plane wave diffraction on a slit was performed. The proposed experimental proof ground can be useful for studying the system of linear edge dislocations space evolution and properties, such as nucleation and annihilation, edge and mixed edge-screw transition.
