Abstract
The process of focusing circularly polarized laser beams by plane diffractive lenses using the Richards-Wolfe formula is considered. It is established that in the focal plane of a light field with circular polarization circles of different radii with the center on the optical axis are formed. In these circular regions polarization vectors are twisted in opposite directions. The appearance of “spin” separation depending on the radius can be explained by the phenomenon of radial spin Hall effect in the focal plane.
期刊介绍：
The journal covers a wide range of issues in information optics such as optical memory, mechanisms for optical data recording and processing, photosensitive materials, optical, optoelectronic and holographic nanostructures, and many other related topics. Papers on memory systems using holographic and biological structures and concepts of brain operation are also included. The journal pays particular attention to research in the field of neural net systems that may lead to a new generation of computional technologies by endowing them with intelligence.
