Learning goals

1. Students should know how to analyse real optical systems and understand their limitations.

2. Students should know how to describe waves and understand the concepts of group velocity, dispersion and interference.

3. Students should know how to deal with polarized light, know how polarizers function and on what they are based.

4. Students should know the ingredients that underlie Fraunhofer diffraction and understand Fresnel diffraction in terms of its essential aspects.

5. Students should know how to analyse refraction and the reflexion of waves between two different media.

6. Students should calculate the interference between waves and understand the importance of interferometric techniques.

7. Students should know how optical fibres, lasers and holograms function and what they are used for.

Teaching method

- theoretical classes written on the black board and projection of transparencies or videos consisting of computational presentations and animations sometimes may also be used simultaneously.

- theoretical-practical classes for problem discussion.

- laboratorial classes; - experimental demonstration classes.

- elaboration of supporting texts covering all the approached subjects in classes.

- elaboration of about 100 solved and discussed problems that are examples of the approached subjects.

- all the classes should always be open to discussion, involving students in it.
