Abstract
A new, low-cost modal analysis method, capable of extracting the structural modes, verifying numeric simulations, and fine-tuning musical instruments is presented. This method uses fiber Bragg gratings and is demonstrated by reconstructing the mode shapes of a marimba bar. To verify the practicality and accuracy of this method, the results are compared to a numerical FEA simulation and experimental results using a scanning laser Doppler vibrometer.
