INTRODUCTION The real-time detection and identification of biological and chemical warfare agents as well as potential toxic industrial gases and improvised explosive devices (IEDs) is of paramount importance for protecting soldiers and first responders on the battlefield and in counterterrorism response at home.

The coupling of the point sensor is accomplished through both electrical and fiber optic cables running along the manipulator structure. The RBI detector is a Raman point sensor or a Raman proximity detector.

These spatially resolved spectra can be processed using a mixture analy sis algorithm coupled with library searching to provide robust identification of threat and nonthreat materials present in complex environmental samples. UGV INTEGRATION The Wolverine is controlled using a radio frequency link between the robot and the operator control unit (OCU)

Fig 20-2.eps operator has access to this video stream and can use it for fine control of the RBI head. The proof of concept consisted of placing a biological toxin simulant, ovalbumin, on a flattened sheet of galvanized iron air-duct material to provide a constant background for the measurement.

is a detection method that can be used to identify chemical and biological hazards in bulk and on surfaces. It is relatively straightforward, requires no sample preparation or consumables, is sensitive, uses only a small sample substrate, is fast (subsecond)

The ultimate launching of a LIBS–Raman sensor payload on a robotics platform will lead to unprecedented capabilities for field applications in both proximity and standoff sensing modes. PHOTON SYSTEMS DEEP UV RAMAN AND FLUORESCENCE DETECTOR PROJECT Photon Systems, Inc., and the NASA Jet Propulsion Laboratory are collaborating on a project to develop an advanced, miniature, low-power, reagentless, robot-mounted, laser-based instrument for real-time detection and classification of trace concentrations of biological and chemical agents on surfaces.

From page 206... ...
While Raman identification of agents requires a spectra library for patternmatching recognition of molecular structure, it can still identify new, unknown agents (such as recombinant chemical agents or explosive structures or genetically altered organisms) by flagging for further investigation the spectra not already present in the library, especially if they closely resemble the spectra of a known agent or class of known agents.
