Optical metrology is used as cross-sectional technology in many disciplines. At first, the basic characteristics of light and its interaction with matter are pointed out in a short fundamental chapter. Subsequently, the tools of optical metrology, i.e. active and passive optical elements are discussed. The main part of the lecture deals with measuring techniques like: geometry measurements, profilometry, shape measurements, spectroscopy, highspeed cameras, infrared imaging, and biophotonics. The students understand the physical functional principles of optical metrology. They have learned the characteristics and limits of optical metrology. Furthermore, they got to know the selection criteria of suitable optical measuring techniques for a given application.

The lecture starts with the fundamentals of linear optics (refraction, diffraction, dispersion etc.). Afterwards, interaction of light and matter is analyzed and fundamentals of lasers are worked out. Important laser systems are discussed and principles of the generation of short light pulses are explained. The principles and applications of non-linear optics are discussed. Optical memories and optical telecommunications are discussed in separate chapters. An outlook on the potential of photonic crystals is given. The students have learned the fundamentals of optical information transfer and retrieval. They have acquired basic knowledge of lasers, linear and non-linear optics and understand the concepts of optical memories (CD, DVD) and optical telecommunication.

The modern cryptographic algorithms provide a reasonable level of security against the known mathematical and analytical cryptanalysis attacks. Breaking a system by means of a physical attack does not infer to the weakness of the algorithm, but of the implementation. In the first part of the lecture, different kinds of physical attacks on cryptographic devices (e.g., a smartcard used for payment, a contactless card used for authentication, and smartphones) are introduced, while we focus later on countermeasures and the methods to make implementations resistant against the known physical attacks. The goal of this lecture is to give an overview about the known physical attacks and most considerably the schemes developed to counter such a kind of attacks.

Dr. Amir Mo­ra­di 5 ECTS MA Lecture and Exercise Project-based work is a large part of the course. In addition to a written exam, there is weekly project work (homework) and a final seminar. All parts have to be worked on individually. To successfully pass the course, the exam must be passed with at least 50% AND the composite final grade must be at least 50%. The final mark is composed as follows: Weekly project work (homework): 30% Written exam: 60%. Final seminar: 20%. This gives a total of 110%. Therefore 10% of the points to be achieved are bonus points. written exam (120 min) studienberatung@ei.ruhr-uni-bochum.de https://www.ei.ruhr-uni-bochum.de/studium/lehrveranstaltungen/533/

The students carry out various interdisciplinary projects in order to learn how to work scientifically. The students will be able to present technical projects, and to develop problem solution strategies and will hence also obtain worthwhile communication skills. Department of Civil and Environmental Engineering RUB main campus None Professors and Assistants of the program Places for 5 guest students available 3 ECTS 2nd Semester / Summer term or 3rd Semester / Winter term Guidance on scientific work The project paper and presentation will be graded. For this purpose, the individual achievements of the students within the project groups are evaluated separately. The evaluation includes: -Written project paper / 75% (100% without a final presentation) – Final presentation / 25% (optional) Dipl.-Ing.
