Engineering Research Equipment Grant: Scanning Acoustic Microscope (SAM)

扫描声学显微镜（SAM）提供了 以非破坏性方式获得关于 材料的弹性性能，分辨率可与 与高放大率光学显微镜相比。 山姆也 允许在不透光的材料中进行此类研究，因此 允许研究地下和地表 特性. 高温下的结构-性能测量 在试图理解 局部不均匀性的分布，表面和 表面下，对骨骼特性的影响。 SAM也很重要， 提高对植入物影响的认识， 骨-植入物界面。 有限元分析（FEA） 被许多人用来设计新的 植入假体，SAM获得的数据是预期的 来显著地改进这种设计计算。

Scanning Acoustic Microscopy (SAM) provides the capability to obtain information in a nondestructive mode on the elastic properties of materials at a resolution comparable to that of high magnification optical microscopy. SAM also permits such studies in materials opaque to light, thus allowing studies of sub-surface as well as surface properties. Structure-property measurements at high resolution are important in attempting to understand the distribution of local inhomogeneities, both surface and sub-surface, on bone properties. SAM is also important to improve the understanding of the effects of implants at bone-implant interfaces. Finite element analyses (FEA) are being used by many people in their attempts to design new implant prostheses, and data obtained by SAM are expected to dramatically improve such design calculations.
