AbstractIn Phase I, Aerius Photonics demonstrated Raman spectroscopy at 785 nm, 980 nm, and 1064 nm, with only 1064 nm-based excitation showing a reduction in fluorescence. In addition, Aerius Photonics and partner Ahura Scientific, demonstrated a breadboard version of an InGaAs-based Raman spectrometer to assess any engineering challenges. By the end of a Phase III, Aerius proposes to develop a handheld 1064 nm based system that uses an extremely low-noise InGaAs array to not only reduce fluorescence, but maintain the SNR ratio achieved by 785 nm bases systems. The InGaAs arrays are based on Aerius"low dark current InGaAs and low noise ROIC experience. This system will substantially reduce the fluorescence present in CCD-based systems, and unmask otherwise obscured spectra. At the end of a successful Phase II, we would deliver a prototype unit build around the FirstDefender core that is capable of identifying chemicals within seconds, and ready to be put into use very quickly.
