Description

technical field [0001] The invention belongs to the technical field of physical experiments, and relates to a multifunctional measuring device for the influence of particle systems on laser signals. Background technique [0002] With the integration and development of traditional communication technology, traditional radar technology and modern laser technology, laser has been widely developed and applied in radar technology and communication technology. Because laser has the characteristics of high brightness, strong directionality, good monochromaticity, and strong coherence, compared with traditional communication technologies, laser communication has the characteristics of large communication capacity, strong confidentiality, strong directionality, and low economic cost. . Correspondingly, the particles suspended in the atmosphere, such as fog, smoke, dust, sand, etc., can scatter and absorb the laser signal, causing the laser signal to be severely attenuated and depola...

AI Technical Summary

Problems solved by technology

Correspondingly, the particles suspended in the atmosphere, such as fog, smoke, dust, sand, etc., can scatter and absorb the laser signal, so that the laser signal will be severely attenuated and depolarized in low-visibility weather.

The particle size distribution, particle concentration, particle humidity, particle charge, and particle chemical composition of the particle system all have varying degrees of influence on the laser. However, which of them are significant factors, currently due to the lack of relevant experimental measurement devices, there is no good research results
