Learning and Teaching Methods
The lecture leads from the basics of optics to the highly specialized techniques of adaptive optics and interferometry. The topics will be presented in thematically structured lectures. Some international experts are invited. To deepen the understanding, the students have to work through individual chapters of textbooks and original literature, which will then be discussed together in the lecture. As a result, the proportion of self-study in this module is high.
PowerPoint. The slides are made available for download in PDF and PowerPoint format.

Description of exams and course work
There will be an oral exam of 25 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using Knowledge and comprehension questions and sample calculations.
For example an assignment in the exam might be:
- What is "Seeing", which parameters are used to describe its properties, outline the Kolmogorov model for turbulence
- Describe the working principle of adaptive optics and its components, give a description in the framework of control theory
- Outline the principles of stellar interferometry and its main components, how are the measurables related to the intensity distribution of the object
The exam may be repeated at the end of the semester.
