ABSTRACT:
Systems and methods for optically scanning multiple object planes are provided. One embodiment is a method for providing multiple object planes in an optical image scanning environment comprising positioning a first optical sensor array to receive an optical signal corresponding to a first object plane located a first distance from the platen and positioning a second optical sensor array to receive an optical signal corresponding to a second object plane located a second distance from the platen.
