Abstract
A system for order alignment of diffractively produced images is provided. The system comprises: a diffractive spatial light modulator (DSLM) configured to provide a computer generated hologram of an image; a substantially coherent light source configured to illuminate the DSLM which responsively produces the image along each of different diffractive order paths; and, at least one set of optical components located along respective diffractive order paths of the DSLM, the at least one set of optical components configured to align at least one respective image diffracted from the DSLM with at least another diffracted image at a common image plane.
