The contact-less acquisition of untreated latent fingerprint traces with various sensing and image processing techniques is an upcoming opportunity in crime scene forensics. Current analyses of imaging sensor systems show the applicability but dependence on several factors e.g. substrate type, latent trace structure and scanning technology. Also, spectroscopy might be used on fingerprints to determine their chemical composition. Multi-sensor devices might cover huge ranges of different… CONTINUE READING
