摘要近年来，基于弹性波成像的一种新的显微镜形式已经发展起来。声学显微镜的优点是它的对比度取决于弹性性质的变化，这与光学显微镜中的对比度机制是根本不同的过程。在某些情况下，扫描声学显微镜的分辨能力上级最好的光学显微镜。这些事实，再加上声学显微镜对光学不透明物体内部成像的独特能力，创造了一种强大的新实验室技术。声学显微镜的设计进行审查，并讨论其工作原理。从一系列的对象与各种技术获得的显微照片进行了说明。地下成像的技术进行了讨论和说明，参考各种结果。概述了未来可能的进展。
Abstract A new form of microscopy, based on imaging with elastic waves, has evolved in recent years. The virtue of the acoustic microscope is that its contrast depends on the variation in elastic properties which is a fundamentally different process from the contrast mechanisms operative in an optical microscope. There are situations where the resolution capability of the scanning acoustic microscope is superior to that of the best optical microscope. These facts, together with the unique capability of the acoustic microscope to image the interior of optically opaque objects, have created a powerful new laboratory technique. The design of the acoustic microscope is reviewed and its principles of operation are discussed. Micrographs obtained with various techniques from a range of objects are illustrated. Techniques for subsurface imaging are discussed and illustrated by reference to a variety of results. An outline is given of possible future advances.
