Abstract
A means of optically recognizing the presence of substances on or within the walls of a transparent object or on the surface of a reflecting object by impinging a bar of light on the object and collecting the reflected or refracted rays of light by means of optical fibers and directing the light onto a photosensitive element connected to a circuit for using said information. The device disclosed is particularly suitable for inspecting glass jars to detect the presence of foreign material on the surface of the jars, such as 'doping' or a mold release compound during manufacture, such as black spots which are undesirable because they have an unsightly appearance. The mold release is a necessary part of the jar manufacture process. The present system involves manual inspection of jars.
