SENSOR FOR CAPTURING A MOVING MATERIAL WEB

A sensor (1) captures a moving material web (2). The sensor (1) has at least one light source (4) and at least one light detector (10). At least one polarizing element (15) is prepared in between, and the polarizing element affects the polarization properties of a light transmitted by the polarizing...

More Information
Summary:A sensor (1) captures a moving material web (2). The sensor (1) has at least one light source (4) and at least one light detector (10). At least one polarizing element (15) is prepared in between, and the polarizing element affects the polarization properties of a light transmitted by the polarizing element (15), according to the function of an electromagnetic field. For instance, a marking, such as a metal strip (13) inside the material web (2), can be captured by the light detector (10) without any problem.
