| Summary |
|---|
| Subject deals with optical communications in free space. Attention is dedicated to directional optical connections and ordinary diffusion optical nets. Significant part content is orientated to IrDa transmission. Basic technologies will be described together with devices, properties of optical communications systems and influence of atmosphere on transmission signals. |
| Learning Outcomes of the Course Unit |
|---|
Understand the basic principles of optical atmospheric communication and their differences in comparison to fiber optical communications.
Learning outcomes are set so that the students are able to identify and apply tasks in the field of optoelectronics and fiberless commnucations.
