A scanning laser acoustic microscope was used to generate growth curves for amphibian limb regeneration. The mechanical properties of the specimen were converted into a visual image that was suitable for the measurements of limb growth. Bone, cartilage, muscle, dermis, and epidermis can be visualized.

2014 The interest of the scanning acoustic microscope previously demonstrated in the biomedical field is extended to microelectronic applications. The properties of penetrating and focusing of acoustic waves in solids are particularly suitable for non destructive observation of surface and subsurface of solid state structure and device such as integrated circuit, epitaxial, implanted and diffus...

An acoustic microscope with mechanical scanning and piezoelectric film transducers for the input and output has been developed for the microscopic examination of materials.1 In the reflection mode it is possible to work with an acoustic wavelength of 0.5 micrometers and a resolution that compares to that of the optical microscope. The elastic images of material surfaces as recorded with this in...

We used the Continuous Wave Scanning Acoustic Microscope to characterize thin film materials. The measurement of the dispersion curve of surface waves and the inversion of this dispersion equation relation, allow to determine the elastic constants, the density or the thickness of a thin layer on a substrate. Besides, it is possible to have qualitative information on the adhesion properties of t...

The authors present a method based on dynamic force microscopy to characterize subnanometer-scale mechanical vibrations in resonant microand nanoelectromechanical systems. The method simultaneously employs the first eigenmode of the microscope cantilever for topography imaging and the second eigenmode for the detection of the resonator vibration. Here, they apply this scheme for the characteriz...

BACKGROUND A correlation between acquired renal cysts in the dialysed kidney and renal cancer has long been debated, but no changes in the physical properties of kidneys at the microscopic level have been reported. The purpose of the present study was to classify the physical properties of the kidneys of patients undergoing haemodialysis at several stages of pathology by use of the scanning aco...
