Abstract
An optical system for illuminating a multi-element spatial light modulator from a multi-emitter laser array such that each element of the modulator sees light from all emitters targets the light onto the two or more rows of elements, without putting light into the gap between the rows, and without putting light in the spaces between the elements. The element illumination may match a complex shape of the elements. A beamsplitter/staggerer is adapted to split the line of laser light into plural parallel lines of light, and to split the parallel lines of light into regions such that substantially all of the light from the illumination system falls onto the elements of the rows without impinging between the rows of elements or between the elements in the rows.
