摘要： The disclosure relates to a substrate material for the improved detection, resolution and imaging of biological material for spectroscopic characterization by Raman of optical imaging spectroscopy. The substrate provides a uniform, optically flat, highly reflective surface which can be made hydrophobic to prevent spreading of the sample and facilitating its optical evaluation. Moreover, the substrate can be coated with a material that does not emit Raman scattered photons when exposed to said illuminating photons. The principles disclosed herein allow a low spectroscopic background particularly suitable for examining small samples or samples having low concentrations of the suspected component.

摘要： A portable device for detecting explosives and other target materials using SWIR spectroscopic imaging, including hyperspectral imaging. The device may comprise a lens, a tunable filter, and a detector. The device may use solar radiation, or may comprise an illumination source such as a laser, to illuminate at target material and thereby produce interacted photons. The device may utilize multi-conjugate liquid crystal filter technology to filter interacted photons. The disclosure also provides for a method for using the portable device comprising illuminating a target material to produce interacted photons. The interacted photons are used to form a SWIR spectroscopic image, which may be a hyperspectral image. This image is analyzed to thereby identify the target material. This analysis may comprise comparing at least one spectrum or image representative of the target material to a reference spectrum or image. This comparison may be accomplished using a chemometric technique.
