An important one is fluid-structure interaction (FSI) which describes the interaction between a flexible object (rotor blade) and the surrounding fluid (wind). However, the acquisition of FSI is complex, and only a few practical concepts are known. This paper presents a measurement setup to acquire real information about the FSI of rotating wind turbines in wind tunnel experiments. The setup consists of two optical measurement systems to simultaneously record fluid (PIV system) and deformation (photogrammetry system) information in one global coordinate system. Techniques to combine both systems temporally and spatially are discussed in this paper. Furthermore, the successful application is shown by several experiments. Here, different wind conditions are applied. The experiments show that the new setup can acquire high-quality area-based information about fluid and deformation.<\/jats:p>","DOI":"10.3390\/s22135014","type":"journal-article","created":{"date-parts":[[2022,7,4]],"date-time":"2022-07-04T23:38:55Z","timestamp":1656977935000},"page":"5014","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["A Wind Tunnel Setup for Fluid-Structure Interaction Measurements Using Optical Methods"],"prefix":"10.3390","volume":"22","author":[{"given":"Simon","family":"Nietiedt","sequence":"first","affiliation":[{"name":"Institute of Applied Photogrammetry and Geoinformatics (IAPG), Jade University of Applied Sciences, Ofener Str. 16\/19, 26121 Oldenburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom T.
