Viewed from inside the tube, this field looks like an accelerating electrical pulse, and it is this pulse that picks up and carries the electrons-or, if the polarity is reversed, the protons.
从腔内看,此电场就如同一个加速电流脉冲,该脉冲可选中并携带电子,或在极性逆转时选中并携带质子。

When that glass is then "read" by a laser, the voxels produce tiny whirlpools of light, the properties of which have already been determined by the polarity of the laser pulse that created each voxel.
