Giga-Hertz ultrasonic microscopy: Getting over the obscurity- A short review on the biomedical applications

Scanning acoustic microscopy investigation of weld lines in injection-molded parts manufactured from industrial thermoplastic polymer

“…A specific feature of SAM is that imaging contrast varies considerably with the distance between the acoustic lens and the specimen. This enables the visualization of subsurface regions depending on the acoustic properties of the specimen ( Gremaud, 2001 ; Ahmed Mohamed and Declercq, 2020 ) and the numerical aperture (opening angle) of the acoustic lens. The ray model illustrated in Fig.…”

Automated tilt compensation in acoustic microscopy

“…Scanning acoustic microscopy (SAM) is a noninvasive and nondestructive imaging technology that has been used for surface and subsurface microscopic imaging of various objects, from industrial to biological specimens, for the last several decades. [1][2][3][4][5] SAM is a noninvasive and nondestructive technology widely used for surface and subsurface microscopic imaging of industrial objects and biological specimens. It is extensively used for microstructural characterisation, surface and subsurface mechanical properties characterisation of materials, structural health monitoring of composite structures, studies of phonon propagations, and detecting surface defects on polymer circuits.…”
