Phase Detection in Acoustic Microscopy
Ultrasonic Imaging, 1990The scanning laser acoustic microscope provides a relatively simple means by which speed of sound data can be collected from biological specimens. By employing a phase detection circuit, phase-contour lines can be superimposed on acoustic micrographs and digitized for direct speed of sound calculations.

This paper details the modifications to an existing ion implanter that were made to adapt it for ion-acoustic microscopy. Results of tests of the technique on samples of cubic zirconia and alumina implanted with nitrogen ions are described. The utility of the technique for monitoring the progress of implantation in metals and ceramics is discussed.

Scanning acoustic microscopy is a form of microscopy based on the generation and detection of elastic waves in solids. The basic mechanism is the interaction of an acoustic wave with a specimen and the consequent generation of acoustic waves inside the material.

Physics Today, 1981
Electron-acoustic microscopy is a new technique enabling us to produce images that show variations in an object's thermal and elastic properties with a resolution on the order of microns. These images appear dramatically different than optical or electron microscope pictures, and contain much information not otherwise available (see figure 1).

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 ...
