Abstract

A method and a portable device for assessing the occurrence of an agent in a sample. A sample is illuminated with photons emanating from a portable device to produce photons reflected, emitted, or absorbed from a set of multiple points in the sample having a defined geometric relationship. The portable device is used to simultaneously illuminate the sample and analyze the photons reflected, emitted, or absorbed from the set of multiple points using spectroscopic methods, including infrared, fluorescence, and UV/visible. The agent assessed may include a hazardous agent, a chemical agent, a biological agent, a microorganism, a bacterium, a protozoan, a virus, and combinations thereof.
