The Application of Photorefractive Effect of Lithium Niobate in the Development of a Biometric Fingerprint Scanner with Unique Sensitivity

Uzoma I. Oduah
Abstract—This research includes the combination of the optical imaging and capacitive imaging to capture the biometric features of the fingerprint. The system therefore shuffles between the optical mode and capacitive mode while scanning. The photorefractive effect of Lithium Niobate is applied in holographic display of the fingerprint image. The developed fingerprint scanner offers improved diffraction efficiency, low power consumption, and maintains a high image resolution using the Volume Holographic Optical Correlator System. The fingerprint scanner system comprises of the sensor for scanning fingerprint, a processor which stores the captured fingerprint database and a software which compares and matches the fingerprint using Fourier series. By capturing and matching the minutia features and fingerprint patterns, the scanner can authenticate a user.

Index Terms—Fingerprint, holography, photorefractive, imaging.
