Presentation Abstract

Optical communications in open space refer to the transmission of a modulated laser beam across the atmosphere in order to establish a closed and safe communication channel. According to the Beer-Lambert law, an optical beam can be absorbed along the path followed in the atmosphere, having different effects on the features of the beam. Likewise, polarization and reflections generates effects in any optical signal.

This work proposes a preliminary study of these communication systems. Which is a recently explored technique, for which it hasn’t been investigated for most of its capabilities and limitations in various scenarios and specific applications. Experiments will be designed by simulating optical effects of the transmission in the atmosphere through an emulsifier substances. In which a measurement of the features of an audio signal transmitted through a diode laser will be in study. It is also intended to make absorption and polarization experiments in order to define thresholds and get a better understanding on the functioning, limitations and advantages of these communications systems.
