scanning beam

基本解释

Helium ion microscopy (HIM) offers the highest spatial resolution surface imaging of any scanning beam method, as well as extremely high surface sensitivity.
氦离子显微镜能够提供所有扫描射线法中最高空间分辨率的表面图像，以及极高的表面灵敏度。
The influences of target motion on dose homogeneity and conformity degree were theoretically studied under the condition of the active raster-scanning beam delivery system.
从理论上研究了在主动型栅扫描束流配送系统下，靶体运动对靶区剂量均匀性以及重离子治疗适形程度的影响。
In order to acquire a high intensity and minimal scanning beam spot, diffraction analysis and optimal results have been presented.
利用衍射分析方法，优化扫描光束参数，获得高强度、高质量扫描光点。

With this, the scanning beam is not directed at any single spot, but moves around, so the plastic does not burn.
ECONOMIST: Recycling
To do that requires scanning the object beam through the target about a hundred different ways.
ECONOMIST: Microscopy
It works by scanning a laser beam across an object and manipulating the reflected light to produce an extremely narrow focal plane.
