PVA TePla OKOS, a Virginia-based manufacturer of industrial ultrasonic non-destructive (NDT) systems, claims to have a solution based on scanning acoustic microscopy (SAM). A non-invasive and ...

Scanning acoustic microscopy, or SAM, is a non-destructive technique used in failure analysis of complex devices. SAM can provide a resolution down to sub-micron thicknesses. SAM is an efficient tool ...

Scanning implementations of photoacoustic microscopy require a sensor to observe every part of the target in a straightforward sequence. One drawback of this approach is that it can take a long time.
