摘要: A sensor system for evaluating an item as it moves includes a sensor assembly including a plurality of emitters and a plurality of detectors disposed about an item movement path. A controller is configured for selectively operating the sensor assembly to set up a first active detection pattern through the item movement path by sequentially and rapidly checking an occlusion status of each of a first plurality of emitter to detector light paths that make up the first active detection pattern, such that only one emitter to detector light path of the first plurality of emitter to detector light paths is checked for occlusion at a given instance.
