Abstract
An item that might be lost is provided with a badge featuring an array of glass beads. In seeking to retrieve such a lost item, an atmospheric-penetrating beam of laser is directed into the search area, and the signals from a reflectometer are monitored. The item having the badge of the array of glass beads is more easily retrievable when lost or mislaid than an item without such badge.
