ABSTRACT:
Systems and methods for optically scanning multiple object planes are provided. One embodiment is a system for optically scanning multiple object planes comprising a platen and an optical head for scanning. The optical head comprises an optical delay element, a first optical sensor array positioned relative to a lens array along an optical path for receiving an optical signal corresponding to a first object plane located a first distance from the platen, and a second optical sensor array positioned relative to the lens array along another optical path for an optical signal corresponding to a second object plane located a second distance from the platen. The optical delay element is configured to increase the effective distance between the lens array and the second optical sensor.
