Techniques are provided for simulating dissemination of at least one target substance in a scene that has been contaminated with the at least one target substance. Data is received from a user to select at least one target substance whose dissemination is to be simulated as well as parameters for the scene within which the simulation is to be performed. Simulation of the dissemination is performed and data can be displayed to illustrate, statistically and/or graphically, the results of the simulation. The simulation may include simulating interrogation of at least one surface in the scene with a sensor that detects ambient or scattered radiation from the at least one surface. Data may then be generated that indicates overlap of an interrogation spot of the sensor with the at least one target substance on at least one surface in the scene. A user may change parameters and repeat the simulation. The data generated by the simulation techniques is useful in designing sensors as well as developing strategies for deployment of sensors for certain applications.

Virtual scene generator and probability of interception system and method

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. In one embodiment, the system can continuously and without interruptions scan a surface from a 1-meter standoff while generating Raman spectral-frames at rates of 25 Hz.

Method, apparatus and system for rapid and sensitive standoff detection of surface contaminants

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.

Method and system for geo-referencing and visualization of detected contaminants

A system and method are provided for detecting non-fluorescing aerosol particles of biological origin within ambient background aerosol particles using Raman spectroscopy.

Raman interrogation of threat aerosols

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.
