ABSTRACT:
Wavefront correction apparatus for correcting a stepped wavefront output produced by certain angles of scan and by certain positions of scan in scanning microlens arrays includes anamorphic transfer optics with diffractive corrections. The transfer optics form the outputs of all of the unit cell trains of the microlens arrays into a unique, separate, linear image at each position of scan of the scanning array. A stepped wavefront corrector is positioned in the path of each linear image, and selected thicknesses of the material in the stepped wavefront corrector are effective to vary the times of optical passage through the stepped wavefront corrector in amounts to restore the wavefront to a continuous, unstepped form at the outlet of the plate.
