Tomographic scanning acoustic microscope system

The Journal of the Acoustical Society of America, 1998
In this paper, a new type of acoustic microscope system using the tomographic image processing technique of STAM (scanning tomographic acoustic microscope) and operation principles of the transmission-mode and detection technique of SAM (scanning acoustic microscope system) is proposed.

Measurement applications of the scanning acoustic microscope

Journal of Alloys and Compounds, 1994
Abstract Measurement methods using a scanning acoustic microscope are discussed. One of them, interpretation of the interference fringes, was used for measurements of the local elastic properties in an SiCSiC composite material by studying the velocity of Rayleigh waves.

Scanning Acoustic Microscope of 3D-Interconnect

AIP Conference Proceedings, 2009
The College of Nanoscale Science and Engineering of the University at Albany in collaboration with International SEMATECH is investigating the use of Scanning Acoustic Microscope (SAM) for analyzing 3D Interconnects. SAM is a non‐destructive metrology technique which utilizes high frequency ultrasound to generate a microscopic image of the internal ...

Scanning Tomographic Acoustic Microscope: A Review

IEEE Transactions on Sonics and Ultrasonics, 1985
On utilise les techniques de reconstruction tomographiques pour traiter les donnees recueillies par un microscope acoustique a laser a balayage. Avantages importants par rapport aux methodes classiques: representation aisee de la sous-surface des objets complexes, lorsque la structure consideree se situe dans divers plans bien definis.

Intermediate temperature scanning acoustic microscope

1998 IEEE Ultrasonics Symposium. Proceedings (Cat. No. 98CH36102), 2002
This report presents a description of and results on the modification of the Scanning Acoustic Microscope (SAM) for use in in-situ observations of material changes at intermediate temperatures (0/spl sim/500/spl deg/C). Described are the key problems and their solutions (i.e., the thermal protection of the transducer and the peripheral equipment, the ...

Scanning Acoustic Microscope (Abstract)

MTT-S International Microwave Symposium Digest, 2005
The acoustic microscope - an instrument based on acoustic radiation at microwave frequencies - is designed for viewing the microscopic detail exhibited in the elastic properties of a given object. The most significant and the most recent improvement has been the introduction of mechanical scanning.

Scanning acoustic pressure microscope-(SAPM)

2000 IEEE Ultrasonics Symposium. Proceedings. An International Symposium (Cat. No.00CH37121), 2002
A new kind of acoustic microscope that uses a new kind of acoustic generator is proposed. Principles of Scanning Acoustic Pressure Microscope (SAPM) are presented. A very short theoretical consideration of acoustic generator is described. A proposal of schematics of SAPM is designed and described.

Image resolution of the scanning acoustic microscope

Applied Physics Letters, 1977
We have measured the spatial frequency response of an experimental scanning acoustic microscope (SAM) at 375 MHz, using an acoustic high-resolution reflection test target consisting of Au bars on a silicon substrate. Although the instrument resolves 1.6-μm line detail quite well, in favorable agreement with theoretical predictions, the shape of the ...

Scanning acoustic microscope with concave transducers

The Journal of the Acoustical Society of America, 1978
Recently, a scanning acoustic microscope has been developed by Quate and Lemons which utilizes acoustic lenses for focusing ultrasonic waves. In this paper, an alternative scanning acoustic microscope is described which utilizes concave film transducers for focusing ultrasonic waves.

The scanning acoustic microscope – a new tool for the materials scientist

Materials Science and Technology, 1986
AbstractScanning acoustic microscopy is a novel method of non-destructive examination enabling images to be formed which show elastic property variations on a microscopic scale. This ability is unique and accounts for the rapid growth of interest in the technique.
