Abstract
The space-and-time correlation function and the associated intensity fluctuation power spectrum of coherent radiation scattered in a vibrating body is analyzed. Experimental spectrograms clearly demonstrate a line structure attributable to periodicity of the motion. The frequency of oscillations is found from the frequency spacing between the harmonics and the oscillation amplitude, from the equivalent number of harmonics in the spectrum.
