The modern techniques of latent fingerprint imaging

Many problems of the fingerprint analysis have been successfully solved. The biometric technologies are still developed and several of them are used in the various applications. Automatically working recognition systems indicate some number of errors. We can observe a lot of scientific and industry works, where number of faults in biometric systems is constantly decreased. Unfortunately, faultless systems do not exist. In the paper different fingerprint acquisition techniques (also tested in the Fingerprint Department of the Central Forensic Laboratory of the Polish Police) will be presented. These techniques concern both fingerprint disclosure and imprints enhancement.
