9.4 Scanning Acoustic Microscopy: SAM
Materials Science Forum, 2001Scanning acoustic microscopy (SAM) was born in the mid-1970's and a few hundred microscopes have been build in the world, including commercially available units. Since contrast is determined by the acoustic properties of the specimen, several unique applications, involving both imaging and property measurement, are recognized [1,2].

Advances in Mechanically Scanned Acoustic Microscopy
1974 Ultrasonics Symposium, 1974Abstract : A scanning acoustic microscope, using the design we have previously described, can now be routinely operated at a frequency of 1 GHz with a corresponding resolution of nearly 1 micron. Operating in transmission a number of biological samples have been imaged.

Scanning acoustic microscopy: a review
Journal of Microscopy, 1983SUMMARYThe main features of the scanning acoustic microscope are reviewed with particular reference to applications in biology and non‐destructive evaluation. Recent developments on imaging the interior of solids are discussed. Proper interpretation of recorded images can lead to maps of velocity and density via the V(z) response.

Scanning Electron Acoustic Microscopy
1988Publisher Summary This chapter introduces complications in the field of scanning electron acoustic microscopy (SEAM) signal interpretation. Any property of the primary electron beam itself or of any of its other interaction products that may cause a mechanical deformation of the sample can cause an SEAM signal.

GIGAHERTZ SCANNING ELECTRON ACOUSTIC MICROSCOPY
2017In Scanning Electron Acoustic Microscopy (SEAM) an electron beam with the beam current impacting a target site is modulated at acoustic or ultrasonic frequencies. The absorbed energy of the electrons results in a time-varying thermal expansion that leads to acoustic and ultrasonic waves to be launched into the substrate.

Scanning Acoustic Microscopy inside Ceramic Samples
1982Since a few years, new materials have been worked out to comply with the contraints of severe operating conditions. A good example is from the ceramic materials, which are potentially very interesting. These compounds are synthesised from very common and cheap raw materials, their mechanical stiffness and strength are high and their general physical ...

Rayleigh Waves in Scanning Acoustic Microscopy
1985The role played by the Rayleigh wave in the acoustic microscope came as a fortuitous surprise when the microscope was used in the reflection mode to examine integrated circuits and other materials having Rayleigh wave velocity greater than the velocity in water. The primary contrast mechanism for such objects is due to the presence of the Rayleigh wave,
