ABSTRACT:
Systems and methods for providing multiple object planes in an optical image scanner are provided. One embodiment is an optical head configured to scan an object, comprising a rod-lens array positioned to focus light reflected off the document, an optical sensor array for receiving light focused through the rod-lens, and a reflective surface variably positioned relative to the rod-lens array for reflecting light from the object to the rod-lens array. Another embodiment comprises a method for providing multiple object planes in an optical image scanner comprising positioning an optical head relative to a platen to locate a primary focal point of a rod-lens array at a first object plane and adjusting the position of an optical sensor array relative to the rod-lens array to relocate the primary focal point of the rod-lens array at a second object plane.
