【 摘 要 】
We propose a slim optical fingerprint sensor for fake fingerprint detection on mobile environment. The sensor proposed in this paper is compact size and slim thickness. Also, it can be used by only the power of smart phone without battery or external power. This sensor has a new lens design and optical path to minimize distortion. This sensor shows detailed images of ridges and valleys characteristic of fingerprints and has a characteristic of being resistant to moisture. The proposed sensor can detect various kinds of fake fingerprint (Paper, rubber, silicone, etc.). Simulations show that the slim optical fingerprint sensor has an effective performance on the results of the fake fingerprint detection rate.
