First Claim
Patent Images
1. A method for detecting an agent in a sample comprising the steps of:
- (a) illuminating a sample with photons emanating from a device to thereby produce Raman-scattered photons from the sample;
(b) passing the Raman-scattered photons through a fiber array spectral translator;
(c) forming a spatially-accurate wavelength resolved image of at least a portion of the sample using the Raman-scattered photons; and
(d) analyzing the spatially-accurate wavelength resolved image using the device to detect patterns characteristic of the agent.

Abstract
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.

13. A system for detecting an agent in a sample comprising:
-
(a) a device comprising a photon source for illuminating a sample with photons to thereby produce Raman-scattered photons from the sample; (b) a fiber array spectral translator for receiving the Raman-scattered photons from the sample and providing the Raman-scattered photons to a detector; (c) a detector for forming a spatially-accurate wavelength resolved image of at least a portion of the sample using the Raman-scattered photons; and (d) means for analyzing the spatially-accurate wavelength resolved image using the device to detect patterns characteristic of the agent. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 34)
