Measuring dimensions or distance of transparent objects, e.g. thickness of thin glasses |
摘要 |
The method involves detecting a first reflection from the surface of the object, and a second reflection after passage through the surface. A signal edge (4) of the resulting evaluation signal (2) is used to determine the parameter being measured. The sensors used may be CCD sensors.
