FINGERPRINTER AUTHENTIFICATION DEVICE USING LOW COHERENCE LIGHT AND AUTHENTIFICATION METHOD USING THE SAME

摘要

The present invention relates to a device and a method for recognizing a fingerprint. The device irradiates low coherence light on a part of a human body through a semi-permeable plate and utilizes light coherence configured to authenticate an endothelial fingerprint, an integumentary fingerprint, and a biometric property by using coherence light between irradiation light configured to reach the human body and be subsequently reflected and reference light configured to be reflected by the semi-permeable plate, not reaching the part of the human body. In the present invention, provided are the device and the method for recognizing a fingerprint capable of being applied to a small electronic device by implementing a wavelength classifier with MEMS technology.
