    Abstract: An approach to noninvasively and remotely detect the presence, location, and/or quantity of a target substance in a scene via a spectral imaging system comprising a spectral filter array and image capture array. For a chosen target substance, a spectral filter array is provided that is sensitive to selected wavelengths characterizing the electromagnetic spectrum of the target substance. Elements of the image capture array are optically aligned with elements of the spectral filter array to simultaneously capture spectrally filtered images. These filtered images identify the spectrum of the target substance. Program instructions analyze the acquired images to compute information about the target substance throughout the scene. A color-coded output image may be displayed on a smartphone or computing device to indicate spatial and quantitative information about the detected target substance. The system desirably includes a library of interchangeable spectral filter arrays, each sensitive to one or more target substances.

    Abstract: According to some embodiments of the present invention, a fine focus microscope includes an objective lens for collecting light from an object being imaged, and a tube lens for forming a first image from light received from the objective lens. The fine focus microscope further includes a fine focus lens for forming a second image from the first image, and an eyepiece for forming a third image from the second image, wherein the third image is viewable by a user. The fine focus microscope further includes a field lens for directing light from the second image to the eyepiece, and a positioning system mechanically coupled to the fine focus lens, the eyepiece, and the field lens. The positioning system changes a position of the fine focus lens, the eyepiece, and the field lens with respect to the objective lens to provide a change in focus of the object being imaged.

    Abstract: A method for utilizing polarization as a scheme for fluorescence removal from UV Raman spectra collected in a standoff detection scheme has been invented. In this scheme, a linearly polarized ultraviolet (UV) laser interacts with a material on a surface or in a container. The material generates Raman scattering with polarization contributions relative to that of the laser. The material possibly fluoresces as well, but the fluorescence is generally unpolarized. By subtracting a scaled version of the perpendicular component from the parallel component of the returned signal both relative to the laser source polarization—it is possible to generate a spectrum that is fluorescence free and contains the strongest features of the Raman scattered light.
