Abstract: Exemplary embodiments of a sensor arrangement may combine various technologies into an integrated sensor system operative to detect and to identify hazardous biological aerosols. An aerosol sampler may collect and concentrate particles acquired from the ambient environment, eliminating or minimizing particles that are potentially not relevant to the ensuing analysis. An integrated electro-optical subsystem or other detection technology may enable fast, accurate measurements of fluorescence characteristics associated with the acquired sample material, and may additionally identify biological agents present in the sample.

Abstract: Techniques and devices for diagnosing tissue via hyperspectral imaging are presented. A three dimensional "image" where one dimension contains spectral information is formed from a region of interest. The spectral content of the image can be analyzed on a pixel-by-pixel basis to determine the presence of certain matter and the spatial extend thereof The techniques are non-invasive and do not require introduction of agents typically required to facilitate interaction with illumination sources.
