Abstract

See full text

Provided is an optical fingerprint acquisition apparatus. The fingerprint acquisition apparatus has an improved optical lens unit and can correct distortion of an image caused by a light refractor. The optical lens unit includes two cylindrical lenses disposed so that an optical axis of incident light does not coincide with a central axis of the lenses. The optical lens unit corrects an image that is distorted into a rectangle by a light refractor, thereby restoring a square shape. In particular, the fingerprint acquisition apparatus is useful in the simultaneous acquisition of multiple fingerprints as well as the acquisition of a single fingerprint.
