  • Patent number: 8395769
    Abstract: A method for assessing the presence of a pathogenic microorganism in a sample. A sample is illuminated to thereby produce a first plurality of interacted photons which may be scattered, emitted, reflected and/or absorbed by the sample. The first plurality of interacted photons are assessed to thereby generate a Raman data set representative of the sample. This Raman data set is analyzed to thereby determine at least one of: the presence of a pathogenic microorganism in said sample and the absence of a pathogenic microorganism in said sample. The Raman data set may comprise at least one of a Raman spectrum and/or a Raman chemical image representative of the sample.

  • Publication number: 20110237446
    Abstract: A system and method to search spectral databases to identify unknown materials, specifically pathogenic microorganisms. A library is provided, having sublibraries containing reference data sets of known materials and test data sets, both generated by at least one spectroscopic data generating instrument. For each test data set, each sublibrary associated with the instrument used is searched. A set of scores for each searched sublibrary is produced, representing the likelihood of a match between the reference data set and test data set. Relative probability values are calculated for each searched sublibrary. All relative probability values are fused producing a set of final probability values, used in determining whether the unknown material is represented through a known material in the library. The known material represented in the libraries having the highest final probability value is reported, if the highest final probability value is greater than or equal to the minimum confidence value.

  • Publication number: 20110102565
    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.
