Patent ID: 8159662

Claim:
A system including an unmanned ground vehicle (UGV) having a Raman sensor, the system comprising: an unmanned ground vehicle (UGV) having a robot arm; a camera mounted on the robot arm; a laser and associated telescope mounted on the robot arm in such a way as to point in substantially a same direction in which the camera is pointed, wherein the telescope comprises an autofocus system that includes a lens that is arranged to image a laser beam spot at a target on to a linear detector array and that is positioned to assess target distance based on parallax, wherein the lens and the linear detector array are arranged along a same axis that is off-axis from an axis along which laser light travels to the target and wherein light reflected from the target is passed directly to the lens without intervening reflection; a data acquisition and control module mounted on the UGV and configured to receive Raman spectral data from the telescope; and a remote base station having a display and a data processing and analysis module that is configured to receive data from the data acquisition and control module.
