ABSTRACT:
To provide a more representative output signal on electro-optical transducers scanning a traveling filament, such as a textile thread than heretofore possible, a beam of light is passed to the filament and the light reflected therefrom is analyzed and transduced into an electrical signal, so that light passing laterally of the filament is eliminated from the pick-up to provide an output signal in the pick-up representative only of the portion of the thread which is actually illuminated.
