Scanning Acoustic Microscopy Equipment ?
Scanning acoustic microscopy (SAM) equipment is used for non-destructive imaging and characterization of materials at high resolution. It utilizes ultrasound waves to probe the sample's surface and subsurface, providing information about its structure, composition, and mechanical properties.
SAM equipment typically consists of a transducer, which generates and detects ultrasound waves, and a scanning system that moves the transducer across the sample. The transducer emits a focused ultrasound beam onto the sample, and the reflected waves are collected and analyzed to create an image.
SAM can be used in various applications, such as semiconductor inspection, material analysis, and biological imaging. It can reveal details that are not visible with other imaging techniques, such as the internal structure of integrated circuits or the subsurface defects in materials.
The resolution of SAM depends on factors like the frequency of the ultrasound waves and the properties of the sample. Higher frequencies provide better resolution but have limited penetration depth. SAM equipment can be operated in different modes, such as pulse-echo mode or pitch-catch mode, depending on the specific requirements of the application.
Overall, scanning acoustic microscopy equipment is a valuable tool for non-destructive imaging and characterization of materials, offering high-resolution insights into their internal structure and properties.

2、 Principle of operation
La microscopie acoustique par balayage (scanning acoustic microscopy en anglais) est une technique d'imagerie non destructive qui utilise des ondes acoustiques pour visualiser et caractériser les propriétés des matériaux. Le principe de fonctionnement de cette technique repose sur l'émission d'une onde acoustique à haute fréquence (généralement de l'ordre du gigahertz) qui est focalisée sur l'échantillon à étudier à l'aide d'une lentille acoustique. L'onde acoustique se propage dans l'échantillon et interagit avec les différentes interfaces et structures présentes.
Lorsque l'onde acoustique rencontre une interface entre deux matériaux ayant des propriétés acoustiques différentes, une partie de l'onde est réfléchie et une autre partie est transmise. Cette réflexion et cette transmission dépendent des propriétés des matériaux et de l'angle d'incidence de l'onde acoustique. En mesurant l'amplitude et la phase des ondes réfléchies et transmises, il est possible de reconstruire une image de l'échantillon.
La microscopie acoustique par balayage permet d'obtenir des images à haute résolution de la surface et de l'intérieur des échantillons. Elle est utilisée dans de nombreux domaines, tels que l'électronique, les matériaux, la biologie et la médecine. Les avancées récentes dans cette technique incluent l'utilisation de transducteurs à ultrasons plus petits et plus sensibles, ce qui permet d'obtenir une meilleure résolution spatiale. De plus, des techniques d'imagerie avancées, telles que la microscopie acoustique par cohérence de phase, ont été développées pour améliorer la résolution en profondeur et la sensibilité de la technique.
