Abstract: The present disclosure provides for a system and method for detecting explosives and other materials in a sample scene. First interacted photons are produced from a target area wherein the first interacted photons are generated via solar radiation. The first interacted photons are assessed to thereby generate a SWIR hyperspectral image. The SWIR hyperspectral image is analyzed to identify an area of interest likely of comprising an explosive material. The area of interest is illuminated using laser light illumination to generate second interacted photons from the area of interest. These second interacted photons are assessed to determine whether it not an explosive material is present in the area of interest. The system and method may be configured in standoff, OTM, static and UGV configurations.

Abstract: A system and method to obtain a variable field of view (FOV) of a sample without requiring an increase in an imaging CCD array size. In a fiber array spectral translator (FAST) based chemical imaging system, the fibers in the fiber bundle may be organized in different 2D “zones”. Each zone may include a predetermined number of fibers. Each 2D zone of fibers at the signal input end is organized as a separate linear array (1D) at the spectrometer slit input end. Depending on the user-selected FOV, one or more zones of fibers may be selected for signal input (into the spectrometer) by a motorized mobile slit port or linear translating stage, which will sequentially scan output from each selected linear fiber array into the spectrometer slit. The user can switch from one FOV size to another, thereby activating the linear translating stage to gather signals from appropriate linear fiber arrays corresponding to fiber zones associated with the selected FOV. A CCD imager may be used to collect optical data and generate 2D spatially accurate wavelength resolved images of the user-selected FOV.
