Summary:Title screen
Based on the review and analysis of well-known scientific works in the field of wireless optical communication, the results of calculating the volumetric scattering coefficients of haze for a visibility range of 10 km are presented, also the article talks about predicting the most likely refractive values. The refraction forecast must meet two main requirements: to provide information on the most favorable “refractive weather” at the location of the optical system for a particular purpose and to provide the most optimal operating mode and the introduction of the necessary corrections. In accordance with this, two types of forecast can be distinguished - long-term and short-term. Estimates of the influence of scattering on the atmospheric path on the contrast of distant objects show that absorbing aerosol leads to a slight change in contrast, and the visibility decreases, understood as the ratio of the luminous flux to the threshold luminous flux for human eyes or a measuring device. The scattering aerosol causes a veil (background) to appear, and therefore a decrease in contrast and a decrease in visibility. This is due to the presence of a bright screen between the observer and the object. The side illumination of the absorbing aerosol does not lead to a significant change in the situation. Illumination of the scattering aerosol results in an additional reduction in contrast.
