Abstract: A system and method for analyzing unknown materials on surfaces including, but not limited to, chemical materials, biological materials, hazardous materials, drug materials, and non-threat materials using SWIR and/or extended range SWIR hyperspectral and spectroscopic techniques. A system comprising a collection optics, a tunable filter, and a first detector for generating a test data set representative of the unknown sample. A second detector, comprising a visible imaging device, may be configured to operate in a scanning mode to locate areas of interest for further interrogation using SWIR. A method comprising generating a SWIR test data set representative of the unknown sample and analyzing the unknown sample to detect, identify and/or distinguish an unknown material as a known material. This analysis may be achieved by comparing the test data set to a reference data set using at least one chemometric technique.

Abstract: A method for multi-target detection and an apparatus for multi-target detection are capable of detecting at least two targets in real time or near real time. The real-time detection or near real time detection can be achieved by at least one of a Recipe Group Approach, an End Member Grouping Approach, and a Pixelated Grouping Based Approach.

Abstract: The present disclosure provides for a system and method for analyzing a sample comprising at least one unknown material. A first location may be scanned to generate a SWIR hyperspectral image. The SWIR hyperspectral image may be generated using dual polarization techniques. The SWIR hyperspectral image may be analyzed to target a second location comprising the unknown material. This second location may be further analyzed using Raman spectroscopic techniques and a Raman data set may be generated. The Raman data set may be further analyzed to associate the unknown material with a know material.

Abstract: A system and method for detecting environmental conditions using SWIR hyperspectral imaging. A method may comprise collecting a plurality of interacted photons from at least one location and passing the interacted photons through a tunable filter, filtering the interacted photons into a plurality of wavelength bands. These filtered photons may be detected and analyzed to determine the presence or absence of an environmental condition. A system may comprise at least one collection lens configured to collect at least one plurality of interacted photons from at least one location and a tunable filter for filtering the interacted photons into a plurality of wavelength bands. The system may further comprise a detector configured to detect the filtered photons and generate at least one hyperspectral image representative of the location. The system may further comprise a processor for analyzing the hyperspectral data set and determining the presence or absence of an environmental condition.
