Course detail

Aerospace Photonics

FEKT-MPA-ASPAcad. year: 2023/2024

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.

Mode of study

Not applicable.

Entry knowledge

The subject knowledge on the Bachelor´s degree level is requested.

Rules for evaluation and completion of the course

Evaluation: 2 optional tests (up to 10 points for both tests), 1 compulsory individual project (up to 20 points, minimum 10 points). The test has a compulsory written part (up to 50 points) and a compulsory oral part (up 20 points). The content of the exam corresponds to the subject annotation.

To get credit, you need to submit an individual project and get at least 10 points for it. To pass the exam, you need to take part in a written and oral exam. 

 


Evaluation of activities is specified by a regulation, which is issued by the lecturer responsible for the course annually.

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.
The graduate of the course will be able to: (a) describe the basic aspects of photonics, photon and optical wave; (b) describe and explain the principle of the passive components function of the photonic system; (c) describe and explain the function of optical detectors; (d) explain the interaction of optical beams with the transmission medium; (e) describe the profile of the atmospheric transmission medium in the horizontal and vertical directions; (f) describe adaptive optics systems and PAT systems; (g) name and describe statistical and stationary parameters of photonic links; (h) calculate the photonic link energy budget; (i) design the photonic link; (j) name, describe and compare different types of photonic links; (k) name and describe optical satellite systems.
