Abstract
A system for sorting parts wherein a part to be sorted is irradiated with wave energy of a single frequency (or very narrow band of frequencies) which interacts with the part. Wave energy emanating from the part is sensed at many spatially separated places to generate an electric signal representative of a characteristic of the amplitude and phase of the detected wave energy at each place. The electric signal so generated is compared with a pre-established signal and any differences therebetween are determined to establish whether the part is within acceptable limits in terms of geometric characteristics, e.g., size, material characteristics and orientation. The part is then acted upon on the basis of the comparison.
