Abstract:
Continuous-scan laser Doppler vibrometry (CSLDV) is a method whereby one continuously sweeps the
laser measurement point over a structure while measuring, in contrast to the conventional scanning LDV
approach where the laser spot remains stationary while the response is collected at each point. The continuous-
scan approach can greatly accelerate measurements, allowing one to capture spatially detailed mode shapes
