RIDGE PATTERN RECORDING SYSTEM

The invention relates to the field of biometrics. The technical result is a reduction in the cost and an increase in the reliability of a ridge pattern recording system which provides high image quality and has small dimensions, a high operating speed and reduced energy consumption. The system comprises 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, in which a beam of radiation with wavelengths less than L is at least five times superior to a beam of radiation with wavelengths greater than L, and the value of L satisfies the condition 0,37·L 1.5 /(A·N·T 1.2 )
