The MILT (Mold Impression Laser Tool) is a small, hand-held instrument currently used by maintenance crews to scan, detect, and measure Space Shuttle Tile damage. It is very fast and easy to use. Within a couple of seconds, the system produces a complete 3D digital map of the tile surface and then automatically finds and quantifies defects. About the size of a teapot, the MILT weighs 2.5 pounds, and wirelessly transmits flaw dimensions and location information to a laptop PC. Thus, the user can easily take measurements up to several meters away from the laptop unencumbered by cables.
