Abstract
An optical sorter includes an intermittent light source configured to intermittently emit light toward a plurality of sorting targets in transit, an optical sensor configured to detect the light associated with one sorting target among the plurality of sorting targets in transit during a plurality of intermittent light scan periods, a determination part configured to determine a foreign object and/or a defective product with respect to the one sorting target based on a signal acquired by the optical sensor, and a light source control part configured to control the intermittent light source. The light source control part is configured to control the intermittent light source in such a manner that, in a case where the intermittent light source is turned on during at least one intermittent light scan period among the plurality of intermittent light scan periods, a lighting period during which the intermittent light source is on and a non-lighting period during which the intermittent light source is off are provided and the lighting period is started at a timing delayed behind a start of the at least one intermittent light scan period in each of the at least one intermittent light scan period.
