FIELD: engineering of devices for producing dactyloscopic maps, possible use in systems for biometric identification of personality.
SUBSTANCE: device contains, optically interconnected, light source, projection system and a system of photo-receiving elements, image processing block, electrically connected to system of photo-receiving elements, and a set of prisms, having finger positioning groove on the surface for perceiving fingerprints, where each prism is installed in rigid guiding elements, ensuring its possible movement along the groove axis independently from other prisms.
EFFECT: simplified design of device, expanded functional capabilities due to production of more complete picture of registration of papillary pattern of each finger.
