Quantitative Acoustic Microscopy
2002Rocks are composites made of grains that are cemented together by different materials. The strength and seismic properties of the rock depend on the stiffness of the cement. Traditional techniques, such as scanning and transmission electron and optical microscopy can help identify variations in type of cement.

The resolving power of the scanning acoustic microscope now rivals that of the optical microscope. Since Calvin Quate and Ross Lemons reported building the first scanning acoustic microscope in 1974, Quate's group at Stanford has been able to improve the resolution of this instrument every year by about a factor of two; they now report they have ...

The field of microscopy as a whole can be said to be in the third and most productive phase of its long history. The first phase began with the work of Van Leehenhoek (1) on the optical microscope, on which refinements and improvements are continuing up to the present time.
