1. A projector, comprising:
a pre-modulator configured to modulate light into a halftone image;
a primary modulator configured to further modulate light of the halftone image into a desired image; and
one or more relay optics configured to transfer the light of the halftone image from the pre-modulator to the primary modulator;
where imperfections of a Point Spread Function (PSF) of the relay optics are compensated by modifying a backlight image used to energize the pre-modulator, wherein the backlight image is composed of a divided sequence, each bit sequence in the divided sequence representing a different partial half-tone image applied to the halftone image, wherein each partial half-tone image implemented for the halftone image includes compensation for the one or more relay optics.
