Claim Text:
1. A system comprising: 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 repetitions of the image along each of different diffractive order paths arranged in a two dimensional matrix, the repetitions each comprising the image such that a same image is produced along each of the different diffractive order paths; and, at least two sets of optical components located along respective diffractive order paths of the DSLM in the two dimensional matrix, the at least two sets of optical components configured to align at least one respective repetition of the image diffracted from the DSLM with at least another diffracted repetition of the image to provide one image at a common image plane that results from a combination of at least two respective repetitions of the image from said respective diffractive order paths aligned at the common image plane to recover otherwise lost light.
