Abstract

The invention relates to an extreme ultraviolet-ray space remote communication system. The extreme ultraviolet-ray space remote communication system comprises an extreme ultraviolet pulse generation modulator, an extreme ultraviolet collimator, an extreme ultraviolet focuser and an extreme ultraviolet detection demodulator; the extreme ultraviolet pulse generation modulator is arranged on the focal point of the extreme collimator and used for modulating a to-be-transmitted digital signal, and the signal is output in an extreme pulse signal form; the modulated extreme pulse signal is transmitted in an orientation manner after being collimated by the extreme ultraviolet collimator; the extreme ultraviolet focuser is used for receiving the extreme ultraviolet pulse signal and focusing the extreme ultraviolet pulse signal, and the extreme ultraviolet detection demodulator which is arranged on the focal point of the extreme ultraviolet focuser is used for demodulating the extreme ultraviolet pulse signal to obtain the to-be-transmitted digital signal.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an extreme ultraviolet ray space long-distance communication system used for inter-satellite communication. Background technique [0002] At present, the research and application of wireless communication has covered radio waves, microwaves to infrared, visible light, ultraviolet and other electromagnetic waves. Driven by the demand for X-ray astronomical observations, the United States and China are carrying out conceptual research on X-ray communication, but extreme ultraviolet ray communication There are no related reports internationally. [0003] As an electromagnetic wave with a shorter wavelength, extreme ultraviolet rays can also be transmitted in space or in a vacuum state without attenuation, so theoretically using extreme ultraviolet rays as an information carrier can also achieve wireless communication. Compared with other electromagnetic wave communications suc...
