摘要：

Optical imaging is used to measure the interface deformation due to small-amplitude lateral vibrations of an axisymmetric liquid bridge with a precision of the order of micrometers. Crucial aspects of the experimental procedure are identified. Comparison with the predictions of the Navier-Stokes equations for zero capillary number shows good agreement, even for oscillation amplitudes much smaller than the pixel size. A possible application of the experimental procedure is to measure the surface tension for zero Bond number. (C) 2007 American Institute of Physics.
