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 spectrometer for detecting hazardous agents

The disclosure relates to methods and apparatus for assessing occurrence of one or more hazardous agents in a sample by performing multipoint spectral analysis of the sample using a portable or hand-held device. Methods of employing Raman spectroscopy and other spectrophotometric methods are disclosed. Devices and systems suitable for performing such multipoint methods are also disclosed.

Method and apparatus for compact spectrometer for multipoint sampling of an object

The disclosure relates to a portable system having a fiber array spectral translator ('FAST') 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 spectrometer for fiber array spectral translator

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.

Method and apparatus for compact birefringent interference imaging spectrometer

A method for the detection and identification of pathogenic microorganisms using Raman scattered light and emitted light. The method may include passing the Raman scattered light and emitted light through a FAST fiber array spectral translator.

Method for detection of pathogenic microorganisms

A method for the detection and identification of pathogenic microorganisms using Raman scattered light and transmitted light in the near infrared spectral region. The method may include passing the Raman scattered light and transmitted light through a FAST fiber array spectral translator.

Pathogenic microorganisms are detected and classified by spectral imaging of the Raman light scattered by the organisms.

Pathogenic microorganisms are detected in a wide field of view and classified by Raman light scattered light from these organisms together with digital pattern recognition of their spectral patterns.
