Abstract

The invention discloses a light beam excitation type fingerprint recognition system. The light beam excitation type fingerprint recognition system mainly comprises a fingerprint reader, a control chip HV, a fingerprint scanning circuit, an image acquiring unit, an imaging lens, an emitter coupling type asymmetric triggering circuit and a light beam excitation type logic amplification circuit, wherein the control chip HV is arranged in the fingerprint reader; the fingerprint scanning circuit is connected with the control chip HV; the image acquiring unit is connected with the fingerprint scanning circuit; the imaging lens is connected with the image acquiring unit; the emitter coupling type asymmetric triggering circuit is arranged between connection points of the fingerprint scanning circuit and the image acquiring unit; and the light beam excitation type logic amplification circuit is connected with the control chip HV. Because the brand-new emitter coupling type asymmetric triggering circuit is arranged on the fingerprint recognition system, the shortcomings that the performance of the traditional fingerprint reader is unstable, and the traditional fingerprint reader cannot recognize fingerprints with dust or water stain are overcome.

Description

technical field [0001] The invention relates to a fingerprint identification system, in particular to a beam excitation type boost filter type fingerprint identification system. Background technique [0002] At present, the existing single-fingerprint identification devices are generally implemented by a fingerprint collector. Not only the functions of collecting, identifying fingerprints and management are relatively simple, but also the identification efficiency is low, and only one user can be 1:1 at the same time. Or 1:N comparison method. At the same time, the recognition accuracy of these current single fingerprint recognition devices is low, and the performance is unstable. Once there is dust or water stains on the finger, it often fails to recognize it continuously. Therefore, how to effectively overcome the defects of single function, low identification efficiency and low precision existing in the existing fingerprint identification system is a top priority for peo...
