Figure Lengend Snippet: Experimental arrangement: ( a ) physical set-up with the sound source, measurement beam, and SLDV measurement grid highlighted, ( b ) block diagram where solid and dashed lines are wired and wireless connections, respectively, α and β are the scanning mirror angle command signals, and γ is the rotary stage angle command signal.
Article Snippet: The resulting vibratory responses were recorded using the SLDV (Polytec PSV-500 Xtra Scanning Laser Vibrometer; Waldbronn, Germany; sensitivity: 306.2 mms −1 V −1 , sensitive range: 20–1250 kHz, velocity resolution: 0.12 μm/s).
