Study of the impact of backscattering interference for visibility of underwater television systems
The adverse effect of the aquatic environment on the quality of underwater vision is manifested not only in the weakening of the luminous flux, but also in the formation of a backscatter interference. This interference is formed by the backward volumetric scattering of light coming from the observed object towards the observer, as well as radiation coming from the side. The work is based on the analysis of various factors affecting the decrease in the brightness of the backscatter interference. On the basis of the theoretical calculations carried out, the authors determined the main ways to reduce the backscatter interference: • reduction of the angles of illumination of floodlights of the projector type; • use of laser illuminators. The scientific solution of this problem, its implementation in conjunction with other measures will ensure an increase in the visibility range of television equipment of underwater vehicles. This will increase the distance of the underwater vehicle to the ground and, as a result, the efficiency of the search engine will increase.
