Robust optical fingerprint sensor to moisture fingerprints
Young-Hyun Baek · 2016
We proposes a robust optical fingerprint sensor to moisture fingerprints. This sensor a new lens and prim design and optical-path change structure is proposed, which shows improvement of difference between a ridge and valley sensing image than typical fingerprint sensor. Simulations show that the optical fingerprint sensor an effective performance in the moisture ten-fingerprints and the result of NIST quality map.
