Laser measurement technology



In the last years a rapid development of Laser measurement technology took place. Powerful laser measuring methods are available for a variety of measuring and inspection tasks. Their applicability and benefit have been demonstrated successfully for offline and inline measurements of physical and chemical quantities. They became best practice in industrial applications.

The underlying dominant characteristics of laser measuring methods is simply the fact, that lasers measure without contact and with the velocity of light. Lasers are predestinated for measuring and inspection tasks in production technology and quality assurance as well as for research and development tasks. Especially the inline inspection of physical and chemical quantities in a production line is an application field of laser measurement technology of increasing importance.

The lecture presents the fundamentals and applications of laser measurement technology. The lecture is directed to students of the disciplines mechanical engineering, electrical engineering and physics in a masters programme. The lectures have an interdisciplinary character. They are built up on the basics of physics, as teached in the first semesters of the respective bachelors programme.

The following topics will be treated in the lectures and exercises: introduction to laser measurement technology – basics, applications, market, development trends; features of laser radiation, interaction of laser radiation with matter, beam shaping and guiding, detection of electromagnetic radiation, laser interferometry, holography, holographic interferometry, speckle metrology, laser triangulation, laser Doppler methods, optical coherence tomography, laser spectroscopy; lasers, terms, safety – standards and rules.

Within the lectures selected topics will be illustrated complementary with the help of computer animations and experiments.
