“Developing Deep UV Raman Standoff Spectrometers for Explosives: Novel Instrumentation and Photophysical Properties”
We are developing deep UV resonance Raman standoff spectrometers to detect trace explosives. For this effort we are developing revolutionary compact UV lasers, ultrahigh efficiency spectrometers and novel imaging spectrometers. We will discuss our rastering instrument and a new imaging instrument that utilizes a novel photonic crystal narrow wavelength band selection optic. We are developing methodologies to detect explosives at standoff distances greater than 2 m. We are exploring the spectroscopic signatures of explosives as well as their photochemistries, which gives rise to specific dynamic spectral signatures. We will discuss the exciting deep UV Raman spectral signatures of NaNO3, NH4NO3, TNT, RDX, PETN and HMX and compare their behavior to the more boring signatures of typical lazy molecules.
