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.

8-568: Is demodulated by the receive optics, and the resulting video sequences can be processed to produce 3-d images. The modulation produces a flickering effect from frame-to-frame in the video imagery. As part of the Orbiter Boom Sensor System , the LDRI is mounted at the end of the boom on a pan - tilt unit (PTU) along with an intensified video camera (ITVC). During 2-dimensional imaging of the reinforced carbon-carbon panels on
12-478: The leading edge of the shuttle's wings, the LDRI is capable of seeing damage as small as a 0.020 in (0.51 mm) crack. During the mission STS-114 , the LDRI was used to obtain 3-D measurements of a loose gap filler on the underside of the orbiter. The LDRI also flew on the subsequent mission, STS-121 . On this mission, NASA TV broadcast live raw video from the LDRI of the entire wing leading edge and nosecap surveys on flight day 2. An earlier version of
