摘要：
We present an experimental method for measuring velocity gradients caused by distortions and rotations of arbitrary light scattering surfaces. The method is sensitive, gauge free and has a fairly high resolution. It is based on the scattering of a coherent plane light wave at the surface and the evaluation of the intensity pattern of the scattered light in the far field by use of a CCD camera. By properly choosing the scattering geometry one can measure specific components of the velocity gradient of the surface.
