Scanning acoustic microscopy คือ
WebPhotoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect.Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband (i.e. MHz) ultrasonic emission. The … WebMar 1, 2001 · Scanning acoustic microscopy is a form of microscopy based on the generation and detection of elastic waves in solids. The basic mechanism is the …
