Offers up-to-date treatment of fingerprint detection with lasers, including basic principles and equipment, established photoluminescence-based detection techniques and a range of emerging techniques. This second edition summarizes information on time-resolved fingerprint detection, transition selection rules, image intensifiers and CCD cameras, uses of photoluminescence in criminalistics, and scientific principles underlying figerprint detection.

"This book. . .should be read carefully by those contemplating installation of a laser to become aware of [its] special needs and limitations. . .. I would highly recommend it for reading by all those in latent fingerprint work, especially those testifying as experts. "
---The Police Chief
". . .a comprehensive treatment of a singular development in the history of forensic identification. It will be of value to those who find, record, and identify fingerprints, and must also explain these activities in adversarial arenas. The book is well-organized and specific sections are easily located....Diagrams and figures assist greatly in the understanding of the science. "
