Acoustic microscopy - Wikipedia
Acoustic microscopy is microscopy that employs very high or ultra high frequency ultrasound. Acoustic microscopes operate non-destructively and penetrate most solid materials to make visible images of internal features, including defects such as cracks, delaminations and voids.
Scanning acoustic microscope - Wikipedia
A scanning acoustic microscope (SAM) is a device which uses focused sound to investigate, measure, or image an object (a process called scanning acoustic tomography). It is commonly used in failure analysis and non-destructive evaluation .
How it works Scanning Acoustic Microscopy (C-SAM)
Scanning acoustic microscopy (SAM), also denominated acoustic micro imaging (AMI) and scanning acoustic tomography (SAT), is a consolidated and recognized tool for non-destructive quality control, inspection and failure analysis in microelectronics components and materials, which is routinely used for the inspection of plastic encapsulated ...
Confocal Scanning Acoustic Microscopy (CSAM) - MuAnalysis
Scanning Acoustic Microscopy (SAM) is a quick, non-destructive analysis technique. SAM uses ultrasound waves to detect changes in acoustic impedances in integrated circuits (ICs) and other similar materials.
Scanning acoustic microscopy for material evaluation
2020年11月5日 · Scanning acoustic microscopy (SAM) or Acoustic Micro Imaging (AMI) is a powerful, non-destructive technique that can detect hidden defects in elastic and biological samples as well as non-transparent hard materials.

2023年1月4日 · A dual-resonant scanning multiphoton (DRSM) microscope incorporating a tunable acoustic gradient index of refraction lens with a resonant mirror is developed for high-speed volumetric imaging.
Acoustic microscopy for materials characterization
2016年1月1日 · Scanning acoustic microscopy (SAM) is a modern, powerful technology for the visualization of the internal structure of materials of a different nature. It uses high frequency ultrasonic waves to get information from inside inhomogeneities and therefore is a sensitive, precise and safe method for materials characterization.
