Course detail

Aerospace Photonics

FEKT-MPA-ASPAcad. year: 2022/2023

Students will get acquainted with basic concepts of photonics, the theory of photons and optical waves, particular components of photonic systems, and laser beam shaping. Students will also get acquainted with optical transmitters and receivers, the interaction of the optical beam with the atmospheric transmission medium and other transmission environments, adaptive optical and PAT systems, statistical and stationary parameters of photonic links, and their energy budget. Students will get an overview of particular photonic communication systems operating in horizontal and vertical directions and will also get acquainted with optical satellite systems. Students will design their own photonic communication system in an individual project.

Aims

The aim of the course is to acquaint students with the principles of photonics and basic components of optical and photonic systems, to explain the principle of laser beam shaping, to explain the principle of optical sources operation, amplifiers, repeaters, and modulators. Another goal is to acquaint students with the principle of laser beam detection, to explain the principle of interaction of optical beams with transmission media. Students will get acquainted with horizontal and vertical photonic communication systems, which include adaptive optical systems or PAT systems. In the course, they will learn to calculate the energy budget of photonic links. The aim of the course is also to acquaint students with specific optical satellite systems.
