ABSTRACT:
A rod-like light collector for collecting light reflected from a photoconductive surface bearing a developed image and scanned by a flying spot scanner with a central core of a relatively rigid transparent material encased by a cladding material having an index of refraction lower than that of the core and an outer light diffusing coating, a portion of which is removed to provide a slit-like aperture for receiving light reflected from the photoconductive surface. The shape of the light receiving aperture may be varied uniformly along the length of the collector with the size of the aperture at the center at a minimum. And, a slit-like axial section of the cladding material opposite the light receiving aperture may be replaced by a highly reflecting, light diffusing coating.
