Laser Dynamic Range Imager

The Laser Dynamic Range Imager (LDRI) is a LIDAR range imaging device developed by Sandia National Laboratories for the US Space Shuttle program. The sensor was developed as part of NASA's "Return to Flight" effort following the Space Shuttle Columbia disaster to provide 2-D and 3-D images of the thermal protection system on the Space Shuttle Orbiter.
