Recent development of two new UV Raman standoff explosive detection systems

Abstract

Alakai Defense Systems has created two new short range UV Raman standoff explosive detection sensors. These are called the Critical Infrastructure Protection System (CIPS) and Portable Raman Improvised Explosive Detection System (PRIED) and work at standoff ranges of 10cm and 1-10m respectively. Both these systems are designed to detect neartrace quantities of explosives and Homemade Explosives. A short description of the instruments, design trades, and CONOPS of each design is presented. Data includes a wide variety of explosives, precursors, TIC/TIM's, narcotics, and CWA simulants

Design and evaluation of spatial heterodyne Raman spectrometer at 785 nm excitation wavelength

“…2 By analyzing the parameters, such as peak position, peak intensity, and peak width in Raman scattering spectra, information on molecular chemical bond vibrations and rotations of the test target can be obtained, which can effectively determine the composition and structure of substances. Due to the advantages of rapidity and non-destructiveness, Raman spectroscopy (RS) has been widely used in various fields, such as food safety, 3,4 hazardous material identification, 5,6 art authentication, 7 geological exploration, 8 biomedical research, 9 materials preparation, 10 and planetary exploration. 11,12 Spatial heterodyne spectroscopy (SHS) is a Fourier transform-based spectroscopic detection technique that has rapidly developed since the 1990s.…”
