Abstract
Apparatus (and method) for parts sorting and the like wherein parts and the like are transported into an interaction region and irradiated with wave energy which interacts with the parts and the like to provide wave energy that emits from the interaction region. The positions of the parts and the like as they move through the interaction region are detected at spaced locations along the path of travel therethrough. The wave energy that emits from the interaction region is sensed to derive a characteristic of the parts and the like at each of the spaced locations to provide signals from which the characteristic can be determined. The signals are analyzed for each spaced location to derive data representative of the characteristic which serves as the basis for sorting.
