  • Patent number: 8189178
    Abstract: A system and method for sampling constituents in air including counting particles in the air to be sampled; collecting samples of accumulated particles; measuring UV response of a sample of accumulated particles only if the particle count exceeds a predetermined threshold; measuring IR response of that sample; and indicating a threat alarm if the IR response matches that of a target within a predetermined threshold.
    Type: Grant
    Filed: June 22, 2009
    Date of Patent: May 29, 2012
    Assignee: Foster-Miller, Inc.

  • Patent number: 7495761
    Abstract: A spectroanalytical system for receiving radiation to be analyzed along a first path includes a grating in the first path with periodic faceted grooves for spatially separating the radiation as a function of wavelength. The blaze angles of the faceted grooves are progressively graded. A multielement detector detects radiation spatially separated by the grating. An optical conditioner is disposed in the first path between the grating and a multielement detector.

  • Patent number: 5814524
    Abstract: The present invention is an optical sensor apparatus for far-field viewing and imaging as well as for the optical detection and analytical measurement of at least one species of analyte in a remotely-positioned fluid sample. The apparatus employs an imaging fiber comprising a fiber optic array and a Gradient Index lens; and utilizes a remotely-positioned solid substrate having light energy absorbing indicator ligands on an external surface for reactive contact with individual species of analytes when present in a fluid sample. The optical sensor apparatus is able to view an object and provide an image of the object located at a pre-set optical distance remote from the imaging fiber. The apparatus is also able to detect and identify, qualitatively and quantitatively, one or more analytes of interest in a flowing solid, gaseous, or liquid sample at remote locations distanced from the imaging fiber itself.
