Abstract

A laser imaging apparatus having a laser source outputting a laser beam and an electronic display device. The electronic display device is positioned downstream from the laser source. The electronic display device is operable to selectively polarize a discrete portion of the laser beam to define a modified portion and an unmodified portion. A polarizing filter is then positioned downstream from the display device so as to prevent passage of either the modified portion or the unmodified portion of the laser beam therethrough so as to define an imaging beam having a specific pattern.
