Abstract
An improved optical scanner has a light source and a focusing element to direct the light to a region of an adjacent moving web. The sensor also includes a second focusing element to focus the reflected light onto a slit having a selected orientation. Electronic elements sense the light passing through the slit and generate an output control signal.
