Vibration of flutes studied by electronic speckle pattern interferometry
Ole J. Løkberg, Ola Kai Ledang · Applied Optics · 1984
This paper describes how electronic speckle pattern interferometry can be used to observe in real time the wall vibrations of simple flutes excited in realistic playing conditions. Dynamic interferograms were created by driving the phase-modulating mirror by means of the amplified sound signal picked up by a microphone. Some preliminary results are given.
