Recent progress has been made on an explosive laser standoff detection system called TREDS-2 constructed from COTS components. The TREDS-2 system utilizes combination of Laser Induced Breakdown (LIBS), Townsend Effect Plasma Spectroscopy (TEPS) and Raman spectroscopy techniques with chemometric algorithms to detect hazardous materials. Extension of the detection capability of the TREDS-2 system on the real-time point detection of chemical, biological, radioactive, and nuclear threats has been tested and presented in this report. System performance of surface detection of a variety of CBRNE materials is shown. An overview of improvements to the explosives detection capabilities is given first. Challenges to sensing some specific CBRN threats are then discussed, along with the initial testing of TREDS-2 on CBRN surrogates on a limited number of surfaces. Signal processing using chemometric algorithms are shown as a demonstration of the system's capabilities. A path forward for using the specific technologies is also provided, as well as a discussion of the advantages that each technology brings to the CBRNE detection effort. |
