Abstract
Currently, wireless laser communication technologies demonstrate high throughput, but the implemented communication systems are not widely used. This feature is due to the low reliability of the communication channels being formed. Recent technological developments have shown successful results in the field of sealing and increasing the noise immunity of communication channels. Therefore, this paper presents a review of modern achievements in the field of multichannel atmospheric optical communication in the visible and near–infrared ranges. The advantages of using diffraction optical elements (DOE) in such systems, which form vortex beams of laser radiation with the required amplitude-phase structure for multiplexing tasks and increasing the noise immunity of information channels, are shown.
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.
