Abstract
An optical imaging device such as a fingerprint imager is disclosed that has an array of micromirrors that allows sequential scanning of areas of a platen in steps. The scanned areas of the platen are transmitted to an image sensor and a composite image constructed from the scanned areas. By transmitting scanned areas of the platen in sections, the image sensor area required is reduced in contrast to prior art optical images that scan the whole platen in a single step.
