Abstract
Imaging techniques are provided to determine the presence of trace chemicals corresponding to various materials of interest. In one example, a method includes receiving a test sample and capturing a plurality of infrared images of the test sample. Each infrared image corresponds to a different range of infrared radiation wavelengths. The method also includes determining a spectral profile of the test sample using the infrared images, comparing the determined spectral profile to a known spectral profile of a material of interest, and determining whether the material is present in the test sample based on the comparing. Additional methods and related devices are also provided.
