Abstract

We present an optical design for a fingerprint scanner that addresses the challenges involved in capturing the prints of rolling fingers. A rolling fingerprint scanner requires a high performance distortion free system with big object space numerical aperture (0.022) and larger capture size (40 × 40 (mm)). We show how these requirements can be achieved with the approach of optical and computational hybrid distortion correction. In addition, dark background illumination is utilized to increase fingerprint contrast.
