Abstract: Systems and methods for fast and sensitive standoff surface-hazard detection with high data throughput, high spatial resolution and high degree of pointing flexibility. The system comprises a first hand-held unit that directs an excitation beam onto a surface that is located a distance away from the first unit and an optical subsystem that captures scattered radiation from the surface as a result of the beam of light. The first unit is connected via a link that includes a bundle of optical fibers, to a second unit, called the processing unit. The processing unit comprises a fiber-coupled spectrograph to convert scattered radiation to spectral data, and a processor that analyzes the collected spectral data to detect and/or identify a hazardous substance. The second unit may be contained within a body-wearable housing or apparatus so that the first unit and second unit together form a man-portable detection assembly.

Abstract: A system and method are provided for visualizing a scene that is monitored for substance contamination. The scene is scanned with a substance detector to detect a substance, such as a harmful chemical or biological substance. The position of the substance is determined. Graphical element data that represents the detected substance in the scene is generated. A displayed view of the scene is augmented with the graphical element data based on the position of the detected substance to show the detected substance in the view of the scene and provide the user with the location and type of detected substance shown with reference to the environment.

Abstract: An apparatus for laser interrogation of surface agents moving relative to the apparatus. A receiver telescope includes a secondary reflector that may compensate for variations in distance from a target to the laser. The secondary reflector relies on a distance to target signal that may be collected at a point substantially away from the target, in the direction of relative motion, to allow a focusing mechanism time to react.
