An overview on Schlieren optics and its applications: Studies on mechatronics

Abstract

This work provides a short overview on the dierent schlieren visualisation methods. The introduction contains a brief explanation of the working principles followed by the historical development of the technique. After a sum-up of the physical theory behind schlieren image, the most important Setups designs are compared and discussed. In context with the research of PhD Student Dirk M oller at the IMES institute of ETH Z urich, the focus was set on the possibilities for an eventual use of schlieren setups for ultrasonic wave imaging. Finally, an overview on the dierent applications of the schlieren method is given. 'Studies on Mechatronics' is a literature research paper that is required for the mechatronics focus in the mechanical engineering bachelor degree.
