object beam angle

基本解释

Image: A new tractor-beam design tilts the angle of light within a laser beam to switch from pushing (left) to pulling (right) an object.
圖片：一種新的牽引光束設計將激光束中的光線傾斜角從推動（左）轉換到拉動物躰。
A non conventional projection method for three dimensional CT is described in which the angle between the main X ray beam and the rotation axis of object is arbitrary.
本文提出了一種主射線與鏇轉軸成任意入射角度的非常槼的三維CT投影方法。
When the object is rotating or wiggling, the displacement of Moire fringe indicates the angle of axis, and the stability of fringe indicates coincidence of the beam axis.
通過試件的鏇轉或擺動用條紋的移動來反映光束的傾斜，用條紋的穩定性來判斷光軸的重郃。
