Monrovia, CA--During SPIE Defense, Security and Sensing in Baltimore (April 30-May 2), new results will be presented by Ondax demonstrating enhanced spectral measurements of explosives and hazardous materials. Results show that many explosive materials exhibit extremely strong spectra in the low-frequency/THz-Raman regime, and when compared to existing Raman detection techniques, this additional data makes them easier to detect and analyze, providing additional means to compare the detailed composition and manufacture of the substances

During the talk, James Carriere, Director of Business Development for Ondax, will present new data collected with the Ondax THz-Raman spectroscopy system from samples provided by the Department of Chemistry and Biochemistry at the University of California, San Diego. According to Carriere, “We have seen an increasing interest in using THz-Raman as a complementary analytical tool in both formulation and analysis of drugs, explosives, and other hazmat materials. Most of these are composed of large, complex molecules that exhibit rich responses in the low-frequency Raman/THz regime.”

The presentation is part of the “Chemical, Biological, Radiological, Nuclear, and Explosives (CBRNE) Sensing” Conference session on “Advances in Standoff Explosives Detection.” The paper, entitled “THz-Raman spectroscopy for explosive, chemical and biological detection” will be presented at 8:20 a.m. on Wednesday, May 1 (paper #8710-26). Equipment demonstrations will also be active during the entire conference at the Ondax booth #1939 in the Exhibit hall.
