The scanning tomographic acoustic microscope (STAM) was proposed in 1982 as a method of improving the resolution capability of the scanning laser acoustic microscope (SLAM) based on the principles of tomography. By modifying the SLAM with a quadrature detector, tomographic projections that contain both the amplitude and phase information of the scattered wavefield can be acquired. Subsequently, multiple projections acquired with different incident waves are combined using the "back-and-forth" propagation algorithm to form the tomographic reconstruction. The first STAM reconstructions have been obtained to experimentally demonstrate the superior resolution capability of the STAM over the SLAM. In this paper, the implementation of the STAM is described, and experimental reconstructions of multiple-layer specimens are demonstrated.
扫描层析声学显微镜（STAM）于 1982 年被提出，作为一种改进基于层析成像原理的扫描激光声学显微镜（SLAM）分辨率能力的方法。通过用正交探测器来修改 SLAM，可以获取包含散射波场的幅度和相位信息的层析投影。随后，使用“来回”传播算法组合用不同入射波获取的多个投影，以形成层析重建。已经获得了第一个 STAM 重建，以实验证明 STAM 相对于 SLAM 的卓越分辨率能力。在本文中，描述了 STAM 的实现，并展示了多层样品的实验重建。
