DEVICE FOR THE OPTICAL INSPECTION OF MOVING SURFACES

In a device for the optical inspection of moving material surfaces (4), a scanning spot (3) is moved along a scanning line perpendicular to the direction of movement of the material. The light reflected as the material surface (4) is traversed is fed to detectors (18, 21) which are situated on eithe...

Zusammenfassung:In a device for the optical inspection of moving material surfaces (4), a scanning spot (3) is moved along a scanning line perpendicular to the direction of movement of the material. The light reflected as the material surface (4) is traversed is fed to detectors (18, 21) which are situated on either side of the material surface (4) to be inspected on a common optical axis (17) which is aligned with the scanning line on the material surface (4).
