Abstract

Systems, apparatus, and methods for providing a micro-scanning system with low settle times for fingerprint image capture are provided. In one embodiment, a flexure apparatus includes a stiffening device and parallelogram structures. The flexure apparatus is configured to move an image sensor to different positions to capture images that can be used to form a composite image according to micro-scanning techniques. The stiffening device allows the resonant frequency of the flexure apparatus to be established at a higher level than the operation frequency of the flexure apparatus, minimizing the settle time required for the flexure apparatus.
