Scanning acoustic microscopy คือ
WebThe scanning acoustic microscope (SAM) is of particular interest for investigating subsurface features in materials such as pores and cracks. The first acoustic microscopes were built in the early 1970s. 1-4 Lemons and Quate 3 developed the first SAM in 1974. Two kinds of acoustic microscopes are generally in use—point focus and line focus.
