Abstract:
Pathogenic microorganisms are detected in a wide field of view and classifie d by Raman light scattered light from these organisms together with digital pattern recognition of their spectral patterns.
Abstract:
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.
Abstract:
A method of simultaneously providing a sample spectrographic signal and a calibration spectrographic signal so as to provide real time calibration of a spectrographic image and a corresponding system.

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.
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.
