  • Patent number: 5912179
    Abstract: Systems and methods for material analysis are disclosed in which an organic sample (e.g., a foodstuff, tissue sample or petroleum product) is illuminated at a plurality of discrete wavelengths which are absorbed by fatty acid and fatty acid oxidation products in the sample. Measurements of the intensity of reflected or absorbed light at such wavelengths are taken, and a analysis of absorbance ratios for various wavelengths is performed. Changes in the reflection ratios are correlated with the oxidative state of fatty acids present in the material.
    Type: Grant
    Filed: January 26, 1998
    Date of Patent: June 15, 1999
    Assignee: Beth Israel Deaconess Medical Center, Inc.
    Inventors: Juan G. Alvarez, Mark Modell
  • Patent number: 5813987
    Abstract: An optical probe collects light emanating from a specimen that selectively andpreferentially represents a localized volume element within the sample, with illuminationintensity and collection efficacy both dropping off away from the localized volume element to limit the integrated contribution from outside the element. For example, the optics provide high peak illumination and high collection efficiency which both overlap in volume elements of a limited size corresponding to a structure or process of the specimen. The resulting collected signal comprising one or more spectral segments is highly correlated with optical characteristics, such as absorbance, scattering or fluorescence characteristics of material in the small volume elements. A processor may apply a previously-derived vector or matrix transform to the collected responses to produce an output.

  • Patent number: 5713364
    Abstract: An optical probe collects light responses from a specimen that selectively and preferentially emanates from a localized volume element within the sample, with illumination irradiance and collection efficiency both dropping off away from the localized volume element, and a processor applies a vector or matrix transform to collected responses to produce an output. The optics provide high peak illumination and high collection efficiency which both overlap in small volume elements that are limited in length, width or depth to correspond to a structure or process of the specimen so that the collected spectra or other responses have high signal strength and enhanced correlation values to small or otherwise inaccessible or masked effects present in macroscopic or submacroscopic regions.

  • Patent number: 4594510
    Abstract: A heat energy measuring system which directs radiation through a sample of a combustible fluid and detects the absorbance of at least one combustible component of the combustible fluid at a selected spectral line, there being at least one spectral line for each combustible component to be examined in the fluid. The system also combines at least one heat energy proportionality factor with the absorbance at each spectral line and sums these combinations to determine the heat energy of the fluid. Where the components to be examined are functional groups, the system measures more generally a physical property of a fluid dependent on the physical characteristics of and the quantity of those functional groups in the fluid.
