| Summary |
|---|
| The subject is focused on selected aspects of optical communication systems in the free space. The emphasis is laid on directed optical fiberless systems operated in the outdoor space as well as optical systems operating in the visible spectral range. Other part of this course is then dealing with modern trends of hybrid fiberless photonic systems also utilizing radio data transmission or satellite/space communication. Significant part of the course is also oriented on IrDa transmissions. During the lectures students will familiarize with main technologies, elements (LED/LD light sources, photodetectors), noises in optical communications or modulation techniques. Influence of atmospheric transmission environment on the optical beam data transfer will be presented as well. |
| Learning Outcomes of the Course Unit |
|---|
| The subject main aim is to understand optical fiberless systems and their differences to optical fiber communication. Study materials are prepared so that students will be able to understand physical principles connected with this communication field as well as identify, apply and solve tasks from the field of optoelectronics and optical fiberless communications. |
