Abstract
Vibration measurements on large and hard-to-reach structures are usually challenging and time-consuming. However, by placing the measurement beam of a laser-Doppler vibrometer with the support of mirrors mounted on drones, vibration measurements at hard-to-access measuring spots are feasible. In this article, we present possible measurement approaches, analyze disturbing effects and demonstrate on the basis of measurement results to which extent they can be reduced.
