Physical modeling of the optical communication system for transmitting audio signals in the modernization of agroengineers

The article is devoted to optical communication systems transmitting an audio signal using laser radiation. A brief historical background for the emergence of this type of communication is outlined and the level of development of atmospheric optical communication lines at the present stage is considered. The significant advantages of using optical communication systems in various conditions are given. The article describes in detail the experimental model developed and manufactured on the basis of household analog equipment for transmitting audio signals over a distance using a laser beam. The scheme, the principles of operation of this installation are considered and its full technical characteristics are given. The areas of application of the created technical device are indicated, its practical significance and the prospects for its use are described, in particular, in the agricultural sector. Attention is paid to the importance of educational modeling in the educational process and the conduct of initial research with it. The application of the created model in the educational process is considered, it is said about the effectiveness of the classes conducted with it. At the same time, it is especially emphasized that the described model was created from analog devices that had been outdated by their technical age, which were being prepared for disposal. Taking into account the fact that modern laboratories require millions of budgets to equip them, the economic effect of such modeling looks very impressive.
