The properties of coherent light passing through a multimode light guide are studied. The spatial and amplitude characteristics of a modulation signal produced by mechanical disturbance of the wave guide are studied using a piezoelectric ceramic transducer. The experimental findings are in qualitative agreement with calculations based on the equations of geometric optics.
