OPTICAL COMMUNICATION SYSTEM THROUGH ATMOSPHERE Russian patent published in 2024 - IPC H04B10/11 

FIELD: electrical communication equipment; physics.

SUBSTANCE: invention relates to communication engineering and can be used to create individual communication channels between stationary or mobile objects, as well as to create centralized telephone and video telephone communication networks, as well as broadcasting networks. System comprises a transmitting station comprising a source of a highly directional beam of monochromatic radiation, as well as a receiving station comprising a lens, in the focal plane of which there is a slit-like diaphragm and a matrix photodetector. Flat beam pattern of the receiving station is formed. Receiving station also has a device for scanning optical radiation along the spectrum in a direction perpendicular to the direction of said slit of the photodetector. When the plane of the beam pattern of the receiving station is aligned with the highly directional beam of the transmitter, communication can be established by receiving radiation scattered by atmospheric air. Angle between the optical axes of the receiver and the transmitter in said alignment plane can be arbitrary.

EFFECT: communication in the absence of direct optical visibility between the receiver and the transmitter, including in case of obstruction by tall buildings, trees or terrain and when it is impossible to install repeaters.
