Abstract: A system for wide-range spectral measurement includes one or more broadband sources, an adjustable Fabry-Perot etalon, and a detector. The one or more broadband sources is to illuminate a sample, wherein the one or more broadband sources have a short broadband source coherence length. The adjustable Fabry-Perot etalon is to optically process the reflected light to extract spectral information with fine spectral resolution. The detector is to detect reflected light from the sample, wherein the reflected light is comprised of multiple narrow-band subsets of the illumination light having long coherence lengths and is optically processed using a plurality of settings for the adjustable Fabry-Perot etalon, and wherein the plurality of settings includes a separation of the Fabry-Perot etalon plates that is greater than the broadband source coherence length.

Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.

Abstract: Disclosed is a portable non-destructive testing (NDT) instrument system that transmits spectrum data measured from a test material sample to a remotely located computer for computation of the sample's atomic element composition. The atomic element composition is subsequently transmitted back to the portable instrument for display to the operator in real time. The precision and accuracy of the compositional computation is improved by the greater processing power of the high performance remote computer. The operator of the NDT instrument may choose to use the remote computer to perform part or all of the compositional computation.

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: Featured are a device (20) and method for the detection of counterfeit pharmaceuticals and/or packaging therefore. Counterfeit pharmaceuticals are detected by visual inspection upon exposing a suspected counterfeit pharmaceutical to one or more light sources having different wavelengths, and observing the differences in color and/or brightness between the suspected counterfeit and a genuine pharmaceutical/packaging. In further embodiments, a image acquisition device acquires an image showing color and/or other visual effect(s) brightness of the suspect counterfeit and this image is compared to an image of a authentic pharmaceutical/packaging.
