Abstract:
1. A biological and chemical detection system comprising: a collector configured to deposit particulates drawn from a fluid stream onto a sample substrate to define a sample area; a first optical device configured to derive first data relative to at least a portion of said sample area, wherein said first data comprises at least one of a fluorescence image, a bright field image or a darkfield image and said processor determines each target location based at least in part, upon a measured contrast of said first data; a processor configured to analyze said first data to determine at least one target location within said sample area; and a second optical device configured to interrogate said sample area at each determined target location to produce interrogation data; wherein said processor is further configured to determine whether said sample area includes predetermined biological or chemical particulates of interest based upon an analysis of said interrogation data and trigger an event if said predetermined biological or chemical particulates of interest are identified.
