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.
