FIELD: device and method for reading and transferring papillary pattern images, used in automated biometric personal identification information systems. ^ SUBSTANCE: anamorphic system for reading papillary patterns contains radiation source, additional radiation source, optical system, including objective with aperture diaphragm and optical element for applying surface with papillary pattern, and multi-element photo-receiver. One of surfaces of optical element is made reflective - spherical or aspheric, convex outwardly. Radiation source and additional radiation source are subject to software-hardware control, and allow receipt of radiation from various wavelength spectrums. Additional radiation source are activated periodically. ^ EFFECT: decreased linear dimensions of optical system, increased trustworthiness of recognition of papillary pattern of living humans and fake, increased quality of original data, received in person identification system, increased contrast of various images of papillary patterns, decreased costs of system. ^ 2 cl, 5 dwg |
