On the base of the lateral shear interferometry, different methods of shearingwave front reconstruction are described in this paper.

The flume experiment shows that the low strength soil in the action of waveshearing force would slide, as the result, strong erosion happens on the bottom.
通过水槽实验发现，底床强度弱区的土体在波浪剪切力作用下，会发生整体滑动现象，造成床面的剧烈侵蚀。

Grating is placed in image space of objective lens, and used as the shearing part. Light wave from reference object and measured object interfered at the image space.
