Abstract

This presentation introduces advances realized at Pendar Technologies on the development of fieldable IR and Raman spectroscopy systems for the detection of residues on surfaces. In the first part of the presentation, we will focus on active standoff infrared hyperspectral imaging of small amounts of biological materials (BG and BT spores) deposited on surfaces using a compact quantum cascade laser array-based system. In the second part, we will discuss the development of a fieldable Raman microscopy system to autonomously analyze the composition of single particles deposited on surfaces. The compact system we developed can be used in the field by non-expert users.
