Spectral Sensor Solutions proposes a combined experimental and analytical evaluation of innovative state-of-the-art technologies to design an optimal portable UV Raman instrument for the detection of trace explosive residues. To accomplish this, we leverage our extensive experience in the phenomenology, spectroscopy, end-to-end modeling, electro-optical engineering and test and evaluation of UV Raman trace chemical and explosives sensors. Our sensor model predicts that our proposed design will meet the demanding requirements as stated in the solicitation. To demonstrate and confirm the performance of our design, we propose to perform technology evaluation experiments using our existing UV Raman sensor as a testbed system. This experimental component of the project will provide crucial verification of the sensor modeling results, providing high confidence that the proposed sensor design will perform as predicted.
