Abstract. Accelerometers are widely used to sense structural response in modal testing. The mass loading and local effects due to accelerometers are not always negligible. The Scanning Vibrometer makes a series of non-contact deflection measurements on a predefined grid using the laser probe to characterise strain at each point instead of attaching individual strain gauges. Thus, the test set-up is fast and very repeatable with no mass loading from an attached transducer. @article{8697726, articleno = {S15}, author = {Marais, Louise and Khettab, Hakim and Li, Yanlu and Segers, Patrick and Baets, Roel and Reesink, Koen and Aasmul, Soren and De Melis, Mirko and Boutouyrie, Pierre}, issn = {1876-4401}, journal = {Artery Research}, language = {eng}, title = {2.6 Validation of the Measurement of Aortic Stiffness by the CARDIS Laser Doppler Vibrometer}, url = {http Siegmund, “Heterodyne laser-Doppler vibrometer with a slow-shear-mode Bragg cell for vibration measurements up to 1.2 GHz ,” 8th International Conference on Vibration A vibrometer is an instrument that measures vibration by firing a laser at a surface .
