Abstract
Technical documentation of crime scenes constitutes an essential stage for the accurate reconstruction of event dynamics and for the production of reliable forensic evidence. Advances in imaging technologies have enabled the development of high-resolution optical capture systems capable of recording forensic traces without physical contact with the evidence. This article presents a technical and operational analysis of two contactless forensic imaging systems: an 8K ultra-high-resolution camera used in homicide scene documentation and the Contactless LITE Evidence Imaging System applied in the detection of latent fingerprints. The experience reported is based on the use of these devices in forensic activities carried out within the Civil Police of the State of Rio de Janeiro. This innovation was implemented by Mr. Alexandre Trece Motta, Director of the Félix Pacheco Identification Institute of the Civil Police of the State of Rio de Janeiro and fingerprint expert. The results demonstrate that the use of multispectral optical technologies combined with ultra-high-resolution image capture allows forensic traces to be documented with a high level of detail, reduces the risk of scene contamination, and preserves evidence integrity for subsequent analyses. It is concluded that contactless imaging systems represent an important advancement for modern criminalistics, improving the precision of forensic documentation, strengthening the chain of custody, and contributing to greater technical robustness of forensic reports submitted to the justice system.
