Abstract:
Chemical imaging technology is a rapid examination technique that combines molecular spectroscopy and digital imaging, providing
information on morphology, composition, structure, and concentration ofa material. Among many other applications, chemical imaging offers
an array of novel analytical testing methods, which limits sample preparation and provides high-quality imaging data essential in the detection of
latent fingerprints. Luminescence chemical imaging and visible absorbance chemical imaging have been successfully applied to ninhydrin, DFO,
cyanoacrylate, and luminescent dye-treated latent fingerprints, demonstrating the potential of this technology to aid forensic investigations. In
addition, visible absorption chemical imaging has been applied successfully to visualize untreated latent fingerprints.
