Abstract

Incoherent strong light beams have been widely used in military, anti-terrorism and anti-drug fields. The transmission of the light beam in the atmosphere is affected by the absorption of the atmosphere, the scattering and refraction of particles in the atmosphere, so that the energy of the strong light beam is continuously attenuated during the transmission process. In order to study the atmospheric transmission characteristics of incoherent strong light beams under different conditions, a theoretical model for the transmission of incoherent strong light in the atmosphere was established, and the Modtran model was used to simulate and calculate the visible light atmospheric transmittance under different visibility conditions. On this basis, the illuminance of the incoherent strong beam after the attenuation of different atmospheric distances is further calculated. The results show that as the visibility decreases, the atmospheric transmittance decreases rapidly, and the illumination of the incoherent strong beam is greatly attenuated. The research results can provide some theoretical support for the in-depth application of incoherent strong beams in military and anti-terrorism fields.
