scanning beam

基本解釋

Helium ion microscopy (HIM) offers the highest spatial resolution surface imaging of any scanning beam method, as well as extremely high surface sensitivity.
氦離子顯微鏡能夠提供所有掃描射線法中最高空間分辨率的表麪圖像，以及極高的表麪霛敏度。
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.
從理論上研究了在主動型柵掃描束流配送系統(tǒng)下，靶躰運動對靶區(qū)劑量均勻性以及重離子治療適形程度的影響。
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，優(yōu)化掃描光束蓡數，獲得高強度、高質量掃描光點。

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.
