A laser eye surgery system includes a laser for producing a laser beam capable of making refractive corrections, an optical system for shaping and conditioning the laser beam, a digital micromirror device (DMD) for reflecting the shaped and conditioned beam toward the eye, and a computer system for controlling the mirrors of the DMD. The computer system generates one-bit resolution images corresponding to ablation layers defining a correction for the eye. The images are then transferred to the DMD for appropriate reflection of the laser beam toward the eye such that the shape of the cornea of the eye is corrected.
