Acoustic microscopy with mechanical scanning—A review
Acoustic waves in liquids are known to have wavelengths comparable to that of visible light if the frequency is in the gigahertz range. The phenomena of Brillouin scattering in liquids is based on such waves. In helium ...
Phase imaging in reflection with the acoustic microscope
(A I P Publishing, 1978-01)
When a polished surface of a single crystal is examined with a converging acoustic beam the reflected signal has a characteristic response that is dependent upon the elastic properties of the reflecting surface. This ...
Reflection coefficient for a lossy liquid–lossless isotropic solid interface
(A I P Publishing, 1979-05)
A theoretical treatment of the reflection problem at a lossy liquid–lossless isotropic solid is given. The calculation results indicate that the reflection coefficient has a peak greater than unity. A physical explanation ...
Modulation transfer function for the acoustic microscope
(The Institution of Engineering and Technology, 1979-05-24)
A simple method to measure the modulation transfer function of an acoustic microscope is described. Theoretical results are compared with experimental measurements. An explanation of `shadowing´ found in acoustic images is given.
An angular‐spectrum approach to contrast in reflection acoustic microscopy
(A I P Publishing, 1978-11)
The scanning acoustic microscope in the reflection mode has proved to be a rather simple and direct means for monitoring the elastic properties of a solid surface. When smooth surfaces of crystalline material are examined ...
Acoustic microscopy: resolution of subcellular detail
(National Academy of Sciences, 1979-07)
Recent advances now permit the use of scanning acoustic microscopy for the analysis of subcellular components. By sequential viewing of identified fixed cells with acoustic, light, and electron microscopy, we have established ...
