    Abstract: An optical detection apparatus includes a scanning device, a sensor, and a distinguishing module. The scanning device is positioned to scan a detection region with a scan light beam, in which the incident angle of the scan light beam varies with time. The sensor is positioned to sense a plurality of reflected scan light beams respectively generated by a plurality of actual touches within the detection region. The distinguishing module is operative to distinguish the actual touches from a plurality of ghost touches according to time signals upon which the plurality of reflected scan light beams are sensed by the sensor.
