Abstract

We have designed, implemented and tested a way of measuring the power spectrum of high amplitude surface fluctuations. A commercial laser vibrometer from Polytec, PI was modified with custom optics and software for this application. The instrument has been tested on levitated drops, levitated bubbles, and on driven fluid surfaces. Independent theory predicted the change in spacing of the fundamental driving frequency and its observed harmonics and subharmonic as the amplitude of the surface waves increases and the system becomes chaotic and turbulent. We observed these predictions along with the appropriate power spectrum for the driving frequency or frequencies and the related harmonics.
