TAGGING COMPOSITIONS AND METHODS

摘要

An ultraviolet laser scanner (15) scans the target (10) to detect the encoding. The output of the ultraviolet laser scanner (15) is monitored by the laser monitor (40) and by the background monitor (20). In addition, filters and detectors (25) are used along with a spectrometer with electronics and at least one display (30). The vertical dashed line separates a fluorescent tag detection portion of the device on the left from the bar code reading portion on the right.
