AbstractThe Neptec Design Group has developed a Laser Camera System (LCS) that can operate as a 3D imaging scanner. The LCS uses an auto-synchronized triangulation scheme to measure range information while two orthogonal scanning mirrors sweep through the field-of-view. The LCS simultaneously records intensity of the reflected laser beam and range information. The intensity data can be used to produce 2D grayscale images as well as to map the intensities onto 3D surface models. The nature of triangulation geometry dictates that such measurements are best for close objects, with range error increasing with the square of object range.The LCS was flown in the payload bay of the shuttle Discovery during mission STS-105. Four scans were taken of the same scene while the shuttle was docked to the International Space Station (ISS). Partially visible ISS elements included the SSRMS (Canadarm2), Multi-Purpose Logistics Module (MPLM), Destiny Lab Module, Node 1 (Unity), Joint Airlock Module (Quest), and several solar arrays.
