Abstract
A detector comprises a row of scanning devices arranged in front of a web to extend transverse to the direction of movement of the web. Each device includes one or two optical illumination fibers associated with a single optical scanning fiber that leads the reflective light toward a photodiode belonging to a row situated at a remote position in the machine. Each of the optical scanning fibers is held in rigid optical relation with an associated spherical or semi-spherical lens by means of an optical glue.
