摘要： A Raman spectroscopy sensor integrated with an unmanned ground vehicle (UGV) includes a UGV having a robot arm and a camera mounted on the robot arm. A laser and telescope associated with a Raman sensor are mounted on the robot arm in such a way as to point in substantially the same direction in which the camera is pointed. A Raman spectral data acquisition and control module is mounted on the UGV and is configured to receive Raman spectral data from the telescope. A remote base station having a display and a data processing and analysis module is configured to receive data from the data acquisition and control module and to display for an operator images from the camera and information related to the Raman sensor. An autofocus system is preferably employed to automatically control telescope focus and thereby enable the Raman sensor to operate over a wide range, e.g., 0.5 m to 10 m.

摘要： According to a present invention embodiment, safety is enhanced for a non-eye-safe limited-range laser sensing system. The laser sensing system typically has an operating range limited to a well-defined spatial interval. A range measurement is utilized to control emissions of the non-eye-safe laser. In particular, when the range to a target is outside the designed spatial interval defining the operating range of the laser sensing system, transmission of the non-eye-safe laser beam is disabled or rendered non-hazardous. In other words, the transmission of the non-eye-safe laser beam is disabled in response to no detection of a hard target within the operating range of the laser sensing system, or when an object is detected between the laser sensing system and the spatial interval that defines the operating range. The target distance may be tracked to change the location (and possibly, width) of the adaptive spatial interval defining the operating range.

摘要： A detection system and method are provided having vehicle-mounted and manportable mobile surveillance capabilities with minimal equipment redundancy. The system comprises a vehicle-mounted sensor unit, a hand-held unit, a manportable unit and a vehicle-mounted air collector unit. The vehicle-mounted sensor unit comprises a spectroscopy subsystem that is configured to direct light onto a surface outside the vehicle and to capture scattered optical energy from the surface outside the vehicle while the vehicle is moving. The hand-held unit may be removably mounted to the air collector unit to interrogate airborne particles in collected air. The hand-held unit is removable from the air collector unit and is connected to the manportable unit by a cable so as to form an integrated portable detection system for mobile surveillance away from the vehicle by a user.
