    Abstract: A sampling accessory coupled to a hand-held reflectance spectrometer provides expanded sampling area which in turn provides better signal averaging from agricultural products which are often inhomogeneous. The sampling accessory includes a sample site repositioning means and a “sample cup” having a base that is transparent to near IR wavelengths.The hand-held reflectance spectrometer includes a shutter responsive to control signals from the control circuitry. When the shutter is closed, a reference measurement may be made. When the shutter is open, a sample measurement is taken.Sample repositioning and data acquisition within the cup may be performed by several means. Fresh sample regions may be exposed through either manual or motor driven sample cup rotation. Alternatively, the sample may be vibrated to induce fresh sample exposure at the window. A further embodiment includes illumination and/or detection paths that may be altered through electrically driven steering optics.

    Abstract: The disclosure provides for a portable device for detecting hazardous agents, including explosives using SWIR hyperspectral imaging. The device may comprise a collection optics, a SWIR multi-conjugate filter, a SWIR camera, and a display. The device may also comprise an RGB camera. The disclosure also provides for a method of using said portable device wherein interacted photons are collected and passed through a SWIR multi-conjugate filter. The interacted photons are detected to generate at least one SWIR hyperspectral image. The SWIR hyperspectral image may be analyzed to determine the presence or absence of a hazardous agent on a target. An RGB image of a target may also be generated and analyzed to survey a sample scene.
