The Scanning Tomographic Acoustic Microscope (STAM) is an instrument capable of performing subsurface imaging of microscopic specimens. Designed around the Scanning Laser Acoustic Microscope (SLAM), the STAM incorporates numerous hardware and software advances which allow automated imaging of the acoustic properties of thick specimens at high resolution. With these modifications the STAM is shown to be capable of image formation for tissue characterization and nondestructive evaluation (NDE) of microscopic specimens. This paper describes the design and operation of the STAM hardware, and software algorithms developed to permit high resolution imaging. Examples are provided to demonstrate the capability of multiple angle and multiple frequency tomographic reconstructions.
扫描断层声学显微镜（STAM）是一种能够对微观标本进行地下成像的仪器。STAM围绕扫描激光声学显微镜（SLAM）设计，融合了众多硬件和软件方面的进步，可对厚标本的声学特性进行高分辨率自动成像。通过这些改进，STAM能够进行图像形成，用于组织表征和微观标本的无损评估（NDE）。本文描述了STAM硬件的设计与操作，以及为实现高分辨率成像而开发的软件算法。还提供了示例以展示多角度和多频率断层重建的能力。
