  • Publication number: 20070211248
    Abstract: A process of rapid and highly accurate analysis of spectral data, includes both a linear scanning (LINSCAN) method and an advanced peak detection method for pattern recognition. One or both of the methods are used to support the detection and identification of chemical, biological, radiation, nuclear and explosive materials. The spectra of various targets can be analyzed by the two spectral analysis methods. These two methods can be combined for dual confirmation, greater accuracy, and to reduced false positives and false negatives, relative to what can be accomplished by either alone.

  • Patent number: 6639733
    Abstract: A highly efficient optical device comprises two opposing active non-spherical optical surfaces defined by a two-dimensional representation that is symmetrically extended to provide a three-dimensional device. A focal area, spaced apart from the optical surface and non-contiguous therewith, is defined by the two opposing active optical surfaces. The active optical surfaces each have a continuous second derivative, and the optical surfaces are defined by a polynomial with an order of at least about twenty. The optical device may comprise a transparent dielectric core, and the optical surfaces may be formed on the core. A receiver may be situated at the focal area to provide a concentrator. An extended light source such as an LED may be situated at the focal area, to provide a collimator. Faceted embodiments can provide a low aspect optical device. In some embodiments a diffuser may be used to transform incident radiation into a predetermined shape.
