Abstract: The invention relates to the field of biometric identification. The technical result consists in decreasing the overall dimensions and increasing the reliability of a system for registering papillary ridge patterns, while providing for reduced cost, high image quality, rapid operating speed and reduced energy consumption. The present system comprises a light source, an element which defines the position of a reading surface, an optical system, and a multi-element image receiver, wherein the reading surface is optically linked to the image receiver by rays passing through a guiding optical element, comprising a refractive surface and a reflective surface, by means of consecutive refraction on the refractive surface, reflection on the reflective surface and total internal reflection on the refractive surface.

Abstract: Disclose a system for recording ridge patterns comprising a light source, a component which determines the position of a scanning surface, an optical system, a multi-element image sensor, an electronic memory and a processing device, wherein the output electronic image from the system is linked by means of merging in the processing device to at least two intermediate images which are linked to the optical image from the scanning surface.
