METHOD FOR REGISTRATION OF PAPILLARY PATTERN AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC A61B5/117 

FIELD: instrument making.

SUBSTANCE: invention is related to personal identification. Method consists in placement of analysed body part with registered papillary pattern onto a transparent base, its illumination with a flow of radiation from source via base and registration of radiation by a receiver. Radiation of source is generated simultaneously in two ranges of wave lengths, one of which is infrared, and registration of radiation by the receiver is done for infrared range in dispersed beams, and for the other one - in reflected ones. Device for registration comprises a transparent base, source of radiation in visible spectrum of waves installed opposite to inlet surface of base and receiver of radiation, installed opposite to outlet surface of base, being electrically connected to processing unit. Opposite to area of finger contact with a perceiving surface, there is an additional source of radiation that radiates in infrared range and is optically connected with source of radiation.

EFFECT: use of invention makes it possible to arrange recognition of a dummy and an actual finger (palm).
