A single-sided NMR sensor to produce depth profiles with microscopic spatial resolution is presented. It uses a novel permanent magnet geometry that generates a highly flat sensitive volume parallel to the scanner surface. By repositioning the sensitive slice across the object one-dimensional profiles of the sample structure can be produced with a space resolution better than 5 microm. The open geometry of the sensor results in a powerful testing tool to characterize arbitrarily sized objects in a non-destructive way.
本文介绍了一种能够产生具有微观空间分辨率深度剖面的单侧核磁共振传感器。它采用了一种新型永磁体几何结构，可产生与扫描仪表面平行的高度扁平敏感体积。通过在物体上重新定位敏感切片，可以生成空间分辨率优于5微米的样品结构一维剖面。该传感器的开放式几何结构使其成为一种强大的测试工具，能够以无损方式表征任意尺寸的物体。
