    Abstract: Macroscopic and microscopic samples are imaged through a spectral filter operable into the short wave infrared, e.g., to approximately 3200 nm. The sample is illuminated for reflective, transmissive, fluorescent and/or Raman imaging by a laser or metal-halide arc beam. The filter has tunable birefringent retarders distributed rotationally and stacked in stages leading up to a selection polarizer. Image forming optics and CCD cameras collect the luminance of each pixel in the spatially resolved image, at multiple wavelengths to which the filter is tuned successively. The filter stages have comb shaped transmission characteristics. Two filter stages with distinctly different characteristics can be cascaded, one or both being tunable. The combined transmission characteristic has narrow passbands where the bandpass peaks of the stages coincide and wide free spectral range where the peaks do not coincide. Embodiments are disclosed for forensic analysis, material composition and morphology, chemical compound identification and detection of biological species.

    Abstract: System and method for spatially and spectrally parallelized FAST. A sample is illuminated to thereby produce interacted photons. The photons are passed through a filter and received at a two-dimensional end of a FAST device wherein said FAST device comprises a two-dimensional array of optical fibers drawn into a one-dimensional fiber stack so as to effectively convert a two-dimensional array of optical fibers into a curvilinear field of view, and wherein said two-dimensional array of optical fibers is configured to receive said photons and transfer said photons out of said fiber array spectral translator device and to a spectrograph through said one-dimensional fiber stack wherein said one-dimensional fiber stack comprises at least two columns of fibers spatially offset in parallel at the entrance slit of said spectrograph. The photons are then detected at a detector to thereby obtain a spectroscopic data set representative of the sample.

    Abstract: A system and method for analyzing a forensic sample. A forensic sample is illuminated nondestructively with light of a first wavelength λ1. A first image of the forensic sample is imaged using light emitted at a second wavelength λ2, the second wavelength filtered by a multi-conjugate tunable filter. A second image of the forensic sample is imaged using the light emitted from the sample at a third wavelength λ3, different from λ2, the third wavelength filtered by a multi-conjugate tunable filter. A calculated image of the forensic image is then created from the first image and the second image. The disclosure also provides for obtaining a processed image by applying a chemometric technique to the calculated image and for identifying the sample as a known forensic material by searching a reference database for a match to either the calculated image or the processed image.
