Applications of a laser radar system with depth accuracy down to 0.2 mm for high accuracy 3-D imaging are described. The system is based on a green pulsed laser triggering a picosecond ICCD camera with data recording of only a few seconds. The submillimeter accuracy gradually degrades at ranges above a few hundred meters due to turbulence, vibrations, etc. As a specific example, we show 3-D accuracy for surface tile inspection of a miniature space shuttle and the resolution of cracks and defects is demonstrated, which is relevant for the planned laser radar inspections from the space shuttle boom and the longer range survey from the International Space Station. By coupling the laser light through a Raman fiber we also demonstrate multispectral 3-D imaging.
