Abstract

The energy of the laser can be greatly reduced, the transmission distance and transmission quality would be affected due to the absorption and scattering of raindrops when transmitting in the rain. Based on Beer-Lambert Law and Mie scattering theory, the impact of raindrop spectrum on 1.06um laser transmission was calculated. Studies have shown that with the increase of rainfall intensity and transmission distance, the laser transmittance decreases. When the rainfall and the transmission distance is consistent, the laser attenuation degree in different raindrop spectrum of rainfall and there are big differences in the change of laser transmittance. This suggests that the raindrop spectrum of rainfall has a big effect on the laser transmission. The study of the effect of raindrop spectrum on laser transmission would help to accurately calculate the laser transmission attenuation characteristic in rain, and improve the quality of the laser transmission in the rain.
