1. Field of the Invention
The present disclosure relates to a device for determining dimensions of a workpiece, and particularly to a device for determining dimensions of a workpiece without having to contact the workpiece.
2. Description of Related Art
Dimensions of many workpieces require determining. At present, simplified dimension determining tools (for example, vernier calipers and micrometers), and complicated determining apparatuses (for example, three-dimensional determining apparatuses or image detecting apparatuses), are all widely used to measure dimensions of workpieces.
In the dimension determining process, most dimension determining tools or apparatuses require contact with or are pressed towards workpieces. Therefore, surfaces or shapes of the workpieces may be damaged.
Therefore, there is room for improvement within the art.
