METHOD AND BIOMETRIC SCANNER FOR IDENTIFYING A PERSON

摘要

The invention is based on the fact that the penetration of electromagnetic radiation into the human body depends on the frequency of the incident wave. Illuminating the palm of the hand with a plurality of intensities of the same monochromatic light sources produces a plurality of vascular maps. The hand (2) of the person to be identified is placed on a supporting means (1) which accommodates an integrated sensor (3) which comprises a reflector (4) in the form of a spherical crown and closed at the top by a diffuser (5), and in the interior of which are arranged an upper plate (6), which supports the light sources, and a lower plate (7) which supports a camera (8), the lens (9) of which passes through the upper plate (6) and extends into a set of filters (10) which pass through the diffuser (5).
