摘要：
A dual two-beam differential interferometer that measures both the amplitude and orientation of propagating, broadband surface acoustic waves. Four beams are focused on a surface. The four reflected beams are separated into two pairs. The two pairs are detected to produce two signals that are used to compute amplitude and orientation.
