Measurement of Influence of a Simulated Atmospheric Environment on a Modulated Optical Beam

Abstract

The diploma thesis deals with Free space optical system and the investigation of the influence of a simulated atmospheric environment on an optical beam. At the beginning of the work, the reader gets acquainted with Free space optical systems and their functions, then the work presents the currently used modulations and also defines atmospheric earth phenomena and their impact on the optical beam. Furthermore, the work records the course of measurements using the designed environment in closable acrylic boxes, in which the environment of rain, fog, temperature and mechanical turbulence were gradually simulated. IoT sensors measuring pressure, temperature and humidity values have been designed to monitor atmospheric conditions. At the end of the work, the author evaluates the results of the simulated measurement.
