Novel optical information transmission system based on plasma spectrum

Abstract

The invention relates to a novel optical information transmission system based on a plasma spectrum. The novel optical information transmission system comprises an optical transmission system laser signal transmitting base station, a laser bending adjusting module, a laser signal oscillation amplifying module and a plasma spectrum signal optical receiving base station. According to the novel optical information transmission system based on the plasma spectrum, base stations only need to be established at the two ends of signal transmission, line laying does not need to be conducted in the transmission process, and a catadioptric lens is adopted to adjust an optical path except for partial object shielding; the cost of line laying and maintenance in current optical fiber transmission is completely saved, an optical signal enters a receiver and then enters a plasma detection pool firstly, a plasma spectrum is excited to be received by a spectrograph, the special property of the plasma spectrum enables the wavelength of each independent signal to be accurately controlled at a nanometer level or even an angstrom level, and the detection accuracy is greatly improved. And the use efficiency of the signal wave band is greatly improved.

Description

technical field [0001] The invention relates to the technical field of information transmission, in particular to a novel optical information transmission system based on plasma spectrum. Background technique [0002] Optical communication technology is a research field that has developed rapidly in recent years and continues to maintain high enthusiasm. It is a communication method that uses light waves as the transmission medium. Light waves and radio waves are both electromagnetic waves, but the frequency of light waves is higher than that of radio waves. The wavelength of radio waves is short, so it has the advantages of wide transmission frequency bandwidth, large communication capacity and strong anti-electromagnetic interference ability. Information is transmitted through certain signals, and the signals play the role of information carriers. Some kind of signal is manifested, with optical signal as the carrier, such as wireless optical communication (atmospheric lase...

Problems solved by technology

Aiming at the deficiencies of the prior art, the present invention provides a new type of optical information transmission system based on plasma spectrum, which has the advantages of improving the use efficiency of the signal band, and solves the problem that the current wireless communication signal is determined by the characteristics of the radio wave itself. The wave band of the signal cannot be accurate to the nanometer level, and the radio wave signal can only be controlled within a certain range, which greatly reduces the problem of the use efficiency of the signal band
