The Chemical Surface Detector (CSD) program is being developed by the Joint Program Executive Office for Chemical and Biological Defense (JPEO-CBD). The system’s primary function is to map contamination, ultimately detecting and warning personnel. It is being designed to continually interrogate the surface and detect and identify contaminants in real time. When fielded, the CSD will become part of the next-generation Nuclear Biological Chemical Sensor Suite for the military’s Stryker Nuclear Biological Chemical Reconnaissance Vehicle (NBCRV). S3 approach to the CSD leverages UV Raman spectroscopy to provide high-speed, on-the-move detection and identification of chemicals on surfaces.
