Abstract

For inspecting and sorting transparent (eg glass) containers 22 having defects in the sidewalls, a light source 52 and a diffuser 48 direct diffused illumination through the sidewall of a container being rotated about its central axis to a camera 42, and the intensity of the illumination is varied transversely of the container axis as a predetermined function of transverse position (e.g. by a graded filter 50). The filter may provide outer regions of uniform intensities, either equal or unequal, and an intermediate region of either a different uniform intensity or transversely varying intensity. The camera 52 may comprise a linear array of light sensitive elements 43 parallel to the container axis. Electronics 54, 56 monitor the output of the elements 43 to identify defects from differences in light detected at adjacent increments of container rotation, and generate signals to reject defective containers from a conveyor which includes selectable exit paths for acceptable and unacceptable containers.
