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.
图片：一种新的牵引光束设计将激光束中的光线倾斜角从推动（左）转换到拉动物体。
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.
本文提出了一种主射线与旋转轴成任意入射角度的非常规的三维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.
通过试件的旋转或摆动用条纹的移动来反映光束的倾斜，用条纹的稳定性来判断光轴的重合。
