Device and method for wireless light scattering communication on basis of Mie scattering

Abstract

The invention discloses a device and method for wireless light scattering communication on the basis of Mie scattering. Original light scattering is achieved through rayleigh scattering based on light and gas molecules in the air, and communication distance is short generally. Light scattering communication is achieved through Mie scattering based on light and aerosol particles in the air, common waveband photoelectric devices can be selected as components required by a system, and remote non-line-of-sight light scattering communication can be achieved by using strong forward light scattering characteristics of the Mie scattering. A corresponding device comprises a light sending device and a light receiving device, the light sending end of the system sends light signals, and the light signals are detected and scattered at the receiving end through scattering of the aerosol particles in the air to achieve communication. The device and method for the wireless light scattering communication on the basis of the Mie scattering reduces requirements on accuracy of an optical antenna in a wireless optical communication system, can establish non-line-of-sight communication link between two long-distance points rapidly, and achieves light scattering communication.

Description

technical field [0001] The invention relates to a wireless light scattering communication device and method based on Mie scattering of light in the atmosphere. Create a non-line-of-sight communication link to achieve efficient scattered light communication. Background technique [0002] Wireless optical communication technology is a short-distance point-to-point wireless communication method based on optical transmission using laser as a carrier and the atmosphere as a transmission medium. It is also called Free Space Optic (FSO). FSO technology does not occupy radio frequency resources, has strong anti-electromagnetic interference ability, good confidentiality, convenient installation and use, and has been widely used. However, the current working method of FSO technology must adopt the LOS (Line Of Sight) link, which requires that there are no obstacles on the communication link. Bring certain difficulty and inconvenience, and can't realize mobility. [0003] Scattering...

AI Technical Summary

Problems solved by technology

However, according to the working principle of ultraviolet light communication, the development of short-wavelength optoelectronic devices suitable for communication that can be selected by the system is still immature. At the same time, the characteristics of Rayleigh scattering determine that the intensity of scattered light in each scattering direction is not much different, so The transmission distance of ultraviolet light communication is relatively short, usually less than 1 km
