Reception of Audio Signals Received from Different Angles by Optical Methods

In this article we will look at the possibilities of receiving audio signals from different angles through optical and optoacoustic methods. An analysis of the optical methods for transmitting information and transmitting audio signals will be performed. A model of a laboratory environment for transmitting audio signals by optical methods, the so-called Li-Fi system, is considered. The laboratory environment is designed to be presented to students and to perform experiments in the laboratory, as well as the opportunity to prepare term papers related to optoelectronics and acoustics.
