ABSTRACT:
In general, used beer, alcoholic drink or medical bottles are collected to be used again. Such used returnable bottles often have defects such as dust and contaminant or cracks, and they must be removed from the bottles before or after the bottle cleaning process. This invention positively satisfies such a requirement. The electro-optic inspection system according to this invention uses a polarized, scanned optical beam and an array of polaroid optical detectors and a logic signal processing system thereby to securely detect the defects on the transparent or semitransparent containers.
