Abstract

The Full Spectrum Imaging System (FSIS-II) was assessed for the detection of latent fingermarks on a variety of
substrates, specifically focusing on UV-C imaging for untreated marks and those that have been treated with
cyanoacrylate (CA). The use of UV-C was effective at the detection of latent fingermarks on a variety of substrates
and UV-C imaging may be effective when UV-A does not provide any fingermark detections on thermal paper. A
Phase 2 and a small Phase 3 trials on aluminium cans were carried out with a detection sequence of UV-C imaging, CA fuming, UV-C imaging, UV-A imaging and BY40. For Phase 2 laboratory trials, the use of initial UV-C
reflection was effective at removing the background and was a useful tool for initial screening. The use of UV-C
was superior to UV-A after CA fuming and provided the highest overall number of high-quality marks. For phase
3 trials, the results showed that BY40 fluorescence was marginally more effective than UV-C imaging of CAtreated marks. This preliminary study shows that the FSIS-II and UV-C imaging can complement other
methods for the detection of latent fingermarks.
