  • Method and apparatus for compact spectrometer for detecting hazardous agents
    Patent number: 7738095
    Abstract: The disclosure relates to a portable system for obtaining a spatially accurate wavelength-resolved image of a sample having a first and a second spatial dimension that can be used for the detection of hazardous agents by irradiating a sample with light, forming an image of all or part of the sample using Raman shifted light from the sample, and analyzing the Raman shifted light for patterns characteristic of one or more hazardous agents.

  • Method and apparatus for compact birefringent interference imaging spectrometer
    Patent number: 7262839
    Abstract: The disclosure relates to a method and apparatus for a compact birefringent interference imaging spectrometer. More specifically, the disclosure relates to a portable system for obtaining a spectrum of a sample. The portable system may include a first photon emission source for illuminating the sample with a first plurality of photons to thereby produce photons scattered by the sample; an optical lens for collecting the scattered photons; a filter for receiving the collected scattered photons and providing therefrom filtered photons; a first photon detector for receiving the filtered photons and obtaining therefrom a spectrum of the sample; and a rejection filter for blocking the photons from said first photon emission source from entering said first photon detector. The disclosure additionally relates to methods of using such portable systems.
