An illumination and detection architecture that illuminates a target for
detecting a material of interest. The architecture includes an
illumination component that illuminates the target using a predetermined
light wavelength known to energize and thereby cause a detectable change
in the desired chemical and/or compounds associated with the target in a
particular way. The change is then captured by an image capture system
and processed to determine the presence or absence detected of the
desired material of interest at the target.
