摘要:
An encoder has a reference scale having periodic structure of atoms or molecules in a predetermined direction, a probe disposed in opposed relationship with the reference scale, the probe being used to detect the structural variation information of the periodic structure of the reference scale, and relative displacement amount detecting means for detecting the amount of relative displacement of the reference scale and the probe along a predetermined direction from the structural variation information obtained by the probe.
